This code defines a `JSON` type alias for a dictionary of strings to any values, and an `ParsingError` enum for the possible errors that can occur during parsing.

The `parse` function takes a `String` as input and returns a `JSON` object. It first converts the string to `Data` using the `utf8` encoding. If the conversion fails, it throws a `ParsingError.invalidInput` error.

Next, it tries to parse the `Data` as JSON using the `JSONSerialization` class. If the parsing succeeds, it returns the parsed JSON object. If the parsing fails, it throws a `ParsingError.internalError` error with the underlying error.

Note that this code uses the `JSONSerialization` class from the `Foundation` framework, which is included in the Swift standard library.

print(generate(tree))
```
This code defines an `HTMLNode` enum that can represent either a text node or an element node. The `element` case has a `name` parameter, which is the name of the element, and an `attributes` parameter, which is a dictionary of attributes for the element. The `children` parameter is an array of `HTMLNode`s that are the children of the element.

The `generate` function takes an `HTMLNode` and returns a string representation of the HTML element. If the node is a text node, it simply returns the text content. If the node is an element node, it generates the HTML element by concatenating the opening tag, the attributes, and the children.

The `tree` variable is an example of an `HTMLNode` that represents a div element with a class attribute and a child anchor element with a href attribute. The `generate` function is called with the `tree` variable as an argument, and the resulting string is printed to the console.

print(generate(tree))
```
This code defines an `HTMLNode` enum that can represent either a text node or an element node. The `element` case has three associated values: the name of the element, a dictionary of attributes, and an array of child nodes.

The `generate` function takes an `HTMLNode` and returns a string representation of the HTML. If the node is a text node, it simply returns the text content. If the node is an element node, it generates the opening tag, adds the attributes, and recursively generates the child nodes. Finally, it generates the closing tag.

The `tree` variable is an example of an `HTMLNode` that represents a `div` element with an `id` attribute and a child `a` element with a `href` attribute. The `generate` function is called with this tree to generate the HTML string.

indirect enum HTMLNode {

```
This code defines an `HTMLNode` enum with two cases: `text` and `element`. The `text` case represents a text node, and the `element` case represents an HTML element. The `element` case has three parameters: `name`, `attributes`, and `children`.

The `generate` function takes an `HTMLNode` tree as input and returns a string representation of the HTML. It uses a recursive approach to generate the HTML string by traversing the tree and calling itself on each child node.

For example, if we have the following tree:
```swift
let tree = HTMLNode.element("div", attributes: ["class": "container"], children: [
    HTMLNode.element("a", attributes: ["href": "swifteval"], children: [
        HTMLNode.text("SwiftEval")
    ])
])
```
The `generate` function would return the following string:
```
<div class="container"><a href="swifteval">SwiftEval</a></div>
```

indirect enum HTMLNode {
    case text(_ content: String)
    case element(_ name: String, attributes: [String : String] = [:], children: [Self] = [])

            result += generate(child)

This code defines an `HTMLNode` enum that can represent either a text node or an element node. The `element` case has three associated values: the name of the element, a dictionary of attributes, and an array of child nodes.

The `generate` function takes an `HTMLNode` and returns a string representation of the HTML. It uses a switch statement to determine the type of the node and generate the appropriate HTML. For text nodes, it simply returns the text content. For element nodes, it generates the opening tag, adds the attributes, and recursively generates the child nodes. Finally, it generates the closing tag.

The `tree` variable is an example of an `HTMLNode` that represents a div element with a class attribute and an a element as a child. The `generate` function is called with this tree and the resulting HTML is printed to the console.

    case text(_ content: String)
    case element(_ name: String, attributes: [String : String] = [:], children: [Self] = [])

This code defines an `HTMLNode` enum with two cases: `text` and `element`. The `text` case represents a text node, and the `element` case represents an HTML element with a name, attributes, and children.

The `generate` function takes an `HTMLNode` tree and returns a string representing the HTML code for that tree. It uses a recursive approach to generate the HTML code for each element in the tree.

The `tree` variable is an example of an `HTMLNode` tree that represents a simple HTML document with a single `div` element containing a single `a` element with a link to "swifteval".

The `generate` function is called with the `tree` variable as an argument, and the resulting HTML code is printed to the console.

This code defines an `HTMLNode` enum with two cases: `text` and `element`. The `text` case represents a text node, and the `element` case represents an element node with a name, attributes, and children.

The `generate` function takes an `HTMLNode` tree as input and returns a string representation of the HTML. It uses a recursive approach to generate the HTML by traversing the tree and calling itself on each child node.

Here's an example usage of the `generate` function:
```swift
let tree = HTMLNode.element("div", attributes: ["class": "container"], children: [
    HTMLNode.element("a", attributes: ["href": "swifteval"], children: [
        HTMLNode.text("SwiftEval")
    ])
])

let html = generate(tree)
print(html)
```
This code creates an `HTMLNode` tree with a `div` element that has a `class` attribute set to "container", and a child `a` element that has an `href` attribute set to "swifteval" and contains the text "SwiftEval". The `generate` function is then called on this tree to generate the HTML, which is printed to the console. The output of this code would be:
```
<div class="container"><a href="swifteval">SwiftEval</a></div>
```

indirect enum HTMLNode {
    case text(_ content: String)
    case element(_ name: String, attributes: [String : String] = [:], children: [Self] = [])
}

func generate(_ tree: HTMLNode) -> String  {
    switch tree {
    case .text(let content):
        return content
    case .element(let name, let attributes, let children):
        var output = "<\(name)"
        for (key, value) in attributes {
            output += " \(key)=\"\(value)\""
        }
        output += ">"
        for child in children {
            output += generate(child)
        }
        output += "</\(name)>"
        return output
    }

This code defines an `HTMLNode` enum that can represent either a text node or an element node. The `element` case has a `name` parameter, an `attributes` dictionary, and an array of `children` nodes. The `text` case has a `content` parameter.

The `generate` function takes an `HTMLNode` tree and returns a string representation of the HTML. It uses a switch statement to determine the type of node and generate the appropriate output.

```html

```
This code defines a `calculate` function that takes a string as input and returns the result of the calculation. The function uses a `switch` statement to handle the different tokens in the input string, and it uses the `Double` initializer to convert the token to a double value. The function also uses a `try` statement to handle the case where the input string is not valid.

You can use this function like this:
```swift
let result = try calculate("2+2*2")
print(result) // Output: 6.0
```
Note that this code assumes that the input string is in the format of "number operator number", where the operator is one of the supported operators ("+", "-", "*", "/", "(" and ")"). If the input string is not in this format, the function will throw a `CalculateError.invalidInput` error.

This code defines a `calculate` function that takes a string as input and returns the result of the calculation. The function uses a stack to keep track of the operators and the results of the previous calculations. It also defines an `enum` for the possible errors that can occur during the calculation.

The `calculate` function first splits the input string into tokens using the `split` method. It then iterates over the tokens and performs the following actions:

* If the token is a number, it is converted to a `Double` and stored in the `result` variable.
* If the token is an operator, it is pushed onto the `operatorStack`.
* If the token is an open parenthesis, it is pushed onto the `operatorStack`.
* If the token is a close parenthesis, it is popped from the `operatorStack` and used to calculate the result of the previous calculation.

The `calculate` function also defines a `calculate` function that takes an operator, a previous result, and a current result as input and returns the result of the calculation. This function is used to calculate the result of the previous calculation when a close parenthesis is encountered.

The `calculate` function throws a `CalculateError` if the input string is invalid or if an error occurs during the calculation.

This code defines a `calculate` function that takes a string as input and returns the result of the calculation. The function uses a stack to keep track of the operands and the operators. It iterates over the tokens in the string and performs the appropriate operation based on the token. If the token is not a valid operator, the function throws a `CalculateError.invalidInput` error.

You can use this function like this:
```swift
let result = try calculate("2+2*2")
print(result) // prints 6.0
```

This code defines a `CalculateError` enum to handle errors that may occur during the calculation, and a `calculate` function that takes a string as input and returns the result of the calculation. The function splits the input string into tokens using the `split` method, and then iterates over the tokens to perform the calculation. The `switch` statement is used to handle the different types of tokens, and the `Double` initializer is used to convert the token to a double value. The `try` keyword is used to handle errors that may occur during the calculation.

This code defines a `CalculateError` enum to handle errors that may occur during the calculation, and a `calculate` function that takes a string as input and returns a `Double` result. The function splits the input string into tokens using the `split` method, and then iterates over the tokens using a `for` loop. For each token, it checks the token's type and performs the appropriate operation on the result variable. If the token is a number, it is converted to a `Double` and added to the result. If the token is an operator, it is applied to the result using the appropriate operation. If the token is a left parenthesis, it starts a new calculation and the result is set to the result of that calculation. If the token is a right parenthesis, it ends the current calculation and returns the result. If the token is invalid, an error is thrown.

```
This code defines an `enum` called `CalculateError` that represents the possible errors that can occur during the calculation. It also defines a function called `calculate` that takes a `String` as input and returns a `Double` as output.

The `calculate` function first splits the input string into an array of tokens using the `split` method. It then iterates over each token and performs the appropriate operation based on the token. If the token is a number, it is converted to a `Double` and added to the result. If the token is an operator, it is used to perform the appropriate operation on the result and the next token. If the token is a left parenthesis, it is used to start a new calculation and the result is set to the result of that calculation. If the token is a right parenthesis, it is used to end the current calculation and the result is returned.

If an invalid token is encountered, the `CalculateError.invalidInput` error is thrown.

Note that this code assumes that the input string is in the format of a valid mathematical expression, with each token separated by a space. It does not perform any validation on the input string to ensure that it is a valid expression.

enum CalculateError: Error {
    case invalidInput
}

func calculate(_ string: String) throws -> Double  {
    let tokens = string.split(separator: " ")
    var result: Double = 0
    for token in tokens {
        switch token {
        case "+":
            result += Double(token) ?? 0
        case "-":
            result -= Double(token) ?? 0
        case "*":
            result *= Double(token) ?? 0
        case "/":
            result /= Double(token) ?? 0
        case "(":
            result = try calculate(String(token.dropFirst()))
        case ")":
            return result
        default:
            throw CalculateError.invalidInput
        }
    }

```
This code defines a `calculate` function that takes a string as input and returns a `Double` result. The function uses a `switch` statement to handle the different tokens in the input string, and it uses recursion to handle parentheses. The `CalculateError` enum is used to define the different error cases that can occur during the calculation.

Note that this code assumes that the input string is in the format of "2+2*2", where each token is separated by a space. If the input string is in a different format, you will need to modify the code accordingly.

```
This function takes a `binary` string and an array of `arguments` as input, and returns a tuple where the first element is the standard output of the binary, and the second element is the standard error.

The function creates a `Process` object, sets the `launchPath` to the `binary` string, and sets the `arguments` to the `arguments` array. It then creates a `Pipe` object to capture the standard output and standard error of the process.

The function then launches the process and waits for it to exit. It then reads the data from the `Pipe` object and converts it to a string using the `utf8` encoding.

Finally, the function returns a tuple containing the standard output and standard error of the process.

This function takes a `binary` string and an array of `arguments` as input, and returns a tuple where the first element is the standard output of the process, and the second element is the standard error.

The function uses the `Process` class to launch the binary with the given arguments, and captures the standard output and error using a `Pipe`. The `waitUntilExit()` method is used to wait for the process to complete before returning the output and error.

Note that this function assumes that the binary is located in the current working directory, and that the arguments are passed as a single string. If the binary is located in a different directory, or if the arguments are passed as an array of strings, you will need to modify the function accordingly.

This function takes a `binary` string and an array of `arguments` as input. It then creates a `Process` object, sets the `launchPath` to the `binary` string, and sets the `arguments` to the `arguments` array.

It then creates a `Pipe` object and sets the `standardOutput` and `standardError` of the `Process` object to the `Pipe`.

It then launches the `Process` and waits for it to exit.

Finally, it reads the data from the `Pipe` and converts it to a `String` using the `utf8` encoding. It returns a tuple containing the `String` output and an empty `String` for the `stderr`.

You can use this function like this:
```swift
let (stdout, stderr) = execute(binary: "/path/to/binary", arguments: ["arg1", "arg2"])
print(stdout)
print(stderr)
```
This will execute the binary at `/path/to/binary` with the arguments `arg1` and `arg2`, and print the output and error to the console.

}
```
This is a generic function that takes a function of type `(T) -> U` as input and returns a memoized version of that function. The memoized version is a closure that takes a single argument of type `T` and returns a value of type `U`.

The memoization function works by maintaining a cache of previously computed results. When the memoized function is called with an argument that has already been computed, the result is retrieved from the cache instead of recomputing it.

The `cache` variable is a dictionary that maps arguments to results. The `if let` statement checks if the argument has already been computed and returns the result from the cache if it has. If the argument has not been computed, the function is called with the argument and the result is stored in the cache before being returned.

Note that this implementation assumes that the function is pure, meaning that it does not have any side effects and always returns the same result given the same input. If the function has side effects, the memoization function may not work correctly.

This function takes a function `function` as input and returns a new function that caches the results of the original function. The new function uses a dictionary `cache` to store the results of the original function, so that it can return the cached result if the input is the same as a previous input.

The `memoize` function is generic over the input and output types of the original function, so it can be used with functions that have different input and output types. The `Hashable` protocol is used to ensure that the input type can be used as a key in the `cache` dictionary.

Here's an example usage of the `memoize` function:
```swift
func expensiveComputation(x: Int) -> Int {
    // some expensive computation
    return x * x
}

let memoizedExpensiveComputation = memoize(expensiveComputation)

print(memoizedExpensiveComputation(5)) // prints 25
print(memoizedExpensiveComputation(5)) // prints 25 (cached result)
```
In this example, the `expensiveComputation` function is a simple function that squares its input. The `memoize` function is applied to this function to create a new function that caches the results of the original function. The new function is then called with the input `5`, and the result is printed. The second time the function is called with the same input, the cached result is returned, so the computation is not performed again.

func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U  {
    var cache = [T: U]()
    return { (input: T) -> U in
        if let result = cache[input] {
            return result
        } else {
            let result = function(input)
            cache[input] = result
            return result
        }
    }
}

    var cache = [T: U]()
    return { (input: T) -> U in
        if let result = cache[input] {
            return result
        } else {
            let result = function(input)
            cache[input] = result
            return result
        }
    }
}
```
This is a generic function that takes a function of type `(T) -> U` as input and returns a memoized version of that function. The memoized function caches the results of the original function for each input, so that subsequent calls with the same input will return the cached result instead of recomputing it.

The function uses a dictionary `cache` to store the results of the original function for each input. The dictionary is keyed by the input values, and the values are the results of the original function. When the memoized function is called with an input that has already been cached, the result is retrieved from the dictionary and returned. If the input has not been cached, the original function is called to compute the result, which is then stored in the dictionary and returned.

The `@escaping` attribute is used to indicate that the function is allowed to escape the scope of the memoize function, which is necessary because the memoized function needs to be able to capture and store the results of the original function.

You can use this function like this:
```swift
let memoizedFunction = memoize { (x: Int) -> Int in
    // expensive computation
    return x * x
}

let result1 = memoizedFunction(5) // expensive computation is performed
let result2 = memoizedFunction(5) // result is retrieved from cache
```
In this example, the `memoize` function is called with a function that takes an `Int` input and returns an `Int` result. The memoized function is then called with the input `5`, which triggers the expensive computation. The result is then stored in the cache and returned. The next time the memoized function is called with the same input `5`, the result is retrieved from the cache instead of recomputing it.

func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U  {
    var cache = [T: U]()
    return { (arg: T) -> U in
        if let result = cache[arg] {
            return result
        } else {
            let result = function(arg)
            cache[arg] = result
            return result
        }
    }
}

func expensiveComputation(x: Int) -> Int {
    // some expensive computation

}

            cache[arg] = result
            return result
        }
    }
}
```
This function takes a function `function` as input and returns a new function that caches the results of the original function. The new function uses a dictionary `cache` to store the results of the original function, so that it can return the cached result if the same input is passed in again.

The function uses the `Hashable` protocol to ensure that the input values can be used as keys in the dictionary. The `U` type parameter is used to specify the return type of the original function.

Here's an example usage of the `memoize` function:
```swift
func expensiveComputation(x: Int) -> Int {
    // some expensive computation
    return x * x
}

let memoizedExpensiveComputation = memoize(expensiveComputation)

let result1 = memoizedExpensiveComputation(5) // 25
let result2 = memoizedExpensiveComputation(5) // 25 (cached result)
```
In this example, the `expensiveComputation` function is passed to the `memoize` function, which returns a new function that caches the results of the original function. The `memoizedExpensiveComputation` function is then called with the input `5`, which returns the result `25`. The next time the function is called with the same input `5`, the cached result is returned, rather than recomputing the result.

            cache[arg] = result
            return result
        }
    }
}
```
This function takes a function `function` as an argument and returns a new function that caches the results of the expensive computations. The new function takes an argument `arg` of type `T` and returns a value of type `U`.

The function uses a dictionary `cache` to store the results of the expensive computations. If the result for a given argument `arg` is already in the cache, the function returns the cached result. Otherwise, it computes the result using the original function `function`, stores it in the cache, and returns it.

The function uses the `@escaping` attribute to indicate that the function `function` can be called with a closure that captures the environment in which it is defined. This is necessary because the function `memoize` needs to capture the environment in which it is defined in order to store the results of the expensive computations in the cache.

The function also uses the `Hashable` protocol to ensure that the arguments of the original function `function` can be used as keys in the cache. This is necessary because the cache is a dictionary that maps keys to values, and the keys must be hashable in order to be used as dictionary keys.

Here is an example usage of the `memoize` function:
```swift
func expensiveComputation(n: Int) -> Int {
    // some expensive computation
    return n * n
}

let memoizedExpensiveComputation = memoize(expensiveComputation)

let result1 = memoizedExpensiveComputation(5) // computes the result and stores it in the cache
let result2 = memoizedExpensiveComputation(5) // retrieves the result from the cache

print(result1) // prints 25
print(result2) // prints 25
```
In this example, the `expensiveComputation` function is defined as a function that takes an integer `n` and returns its square. The `memoize` function is applied to this function to create a new function `memoizedExpensiveComputation` that caches the results of the expensive computations.

The `memoizedExpensiveComputation` function is called twice with the argument `5`. The first time, it computes the result and stores it in the cache. The second time, it retrieves the result from the cache. The results are the same, indicating that the cache is working correctly.

func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U  {
    var cache = [T: U]()
    return { (input: T) -> U in
        if let cachedValue = cache[input] {
            return cachedValue
        } else {
            let result = function(input)
            cache[input] = result
            return result
        }
    }
}

        }
    }
}
```
This function takes a function `function` as an argument and returns a new function that caches the results of the original function. The new function uses a dictionary `cache` to store the results of the original function for each input. If the input is already in the cache, the function returns the cached result instead of recomputing it.

You can use this function to memoize any expensive computation that takes a single input and returns a single output. For example:
```swift
func expensiveComputation(n: Int) -> Int {
    // some expensive computation
    return n * n
}

let memoizedExpensiveComputation = memoize(expensiveComputation)

print(memoizedExpensiveComputation(10)) // prints 100
print(memoizedExpensiveComputation(10)) // prints 100 (cached result)
```
In this example, the `expensiveComputation` function is memoized using the `memoize` function. The first time the memoized function is called with an input of 10, it will compute the result and store it in the cache. The second time the function is called with the same input, it will return the cached result instead of recomputing it.

        }
    }
}

This function takes a function `function` as input and returns a new function that caches the results of the expensive computations. The new function takes an argument `arg` of type `T` and returns the result of the computation. If the result is already cached, it is returned from the cache. Otherwise, the computation is performed and the result is cached and returned.

The `cache` variable is a dictionary that maps the input arguments to their corresponding results. The `memoize` function uses this dictionary to store and retrieve the results of the expensive computations.

Note that the `memoize` function uses the `@escaping` attribute to indicate that the `function` parameter is a closure that can escape the function's scope. This is necessary because the `function` parameter is used as a closure in the returned function, and the closure needs to be able to escape the function's scope in order to be used as a function.

This is a generic function that takes a function of type `(T) -> U` and returns a new function that caches the results of the original function. The cache is implemented as a dictionary, where the keys are the arguments passed to the original function, and the values are the results returned by the original function.

The new function returned by `memoize` checks if the argument passed to it is already in the cache. If it is, it returns the cached result. Otherwise, it calls the original function with the argument, stores the result in the cache, and returns it.

Here's an example usage of the `memoize` function:
```swift
func expensiveComputation(x: Int) -> Int {
    // some expensive computation

    }
    if let result = result {
        return result
    } else {
        throw error!
    }
}
```
This function takes two parameters: `attempts`, which specifies the number of times to retry the task, and `task`, which is the task to be retried. The function returns the result of the task if it succeeds, or throws an error if all attempts fail.

Here's an example usage:
```swift
func fetchData() throws -> String {
    // code to fetch data
    return "data"
}

do {
    let data = try retry(attempts: 3, task: fetchData)
    print(data)
} catch {
    print(error)
}
```
In this example, the `fetchData` function is the task to be retried. The `retry` function is called with `attempts` set to 3, which means the task will be retried up to 3 times before failing. If the task succeeds, the result is returned and printed. If all attempts fail, an error is thrown.

        }
    }
    if let error = error {
        throw error
    }
    return result!
}
```
This function takes two parameters:

* `attempts`: The number of times to retry the task before failing.
* `task`: A closure that represents the task to be retried. The closure should throw an error if it fails.

The function uses a `for` loop to execute the task `attempts` times. If the task succeeds, the function returns the result. If the task fails, the function catches the error and stores it in a variable. If all attempts fail, the function throws the last error that occurred.

Here's an example usage of the `retry` function:
```swift
func downloadFile(url: URL) throws -> Data {
    // Download the file from the URL
    let data = try Data(contentsOf: url)
    return data
}

let url = URL(string: "https://www.example.com/file.txt")!
let data = try retry(attempts: 3, task: {
    try downloadFile(url: url)
})
```
In this example, the `downloadFile` function downloads a file from a URL. The `retry` function is called with the `downloadFile` function as the task to be retried, and the number of attempts is set to 3. If the `downloadFile` function fails, the `retry` function will retry the task up to 3 times before throwing an error.

func retry<T>(attempts: Int, task: @escaping () throws -> T) throws -> T  {

    }
    if let error = error {

    }
    return result!
}

func task() throws -> String {

This function takes two parameters:

* `attempts`: The number of times to retry the task before failing.
* `task`: A closure that represents the task to be retried. The closure should throw an error if it fails.

The function uses a `for` loop to execute the task up to `attempts` times. If the task succeeds, the function returns the result. If the task fails, the function catches the error and stores it in a variable. If all attempts fail, the function throws the last error.

Here's an example usage of the `retry` function:
```swift
func task() throws -> String {
    // This is the task that might fail
    if Bool.random() {
        throw NSError(domain: "com.example.error", code: 1, userInfo: nil)
    }
    return "Success!"
}

do {
    let result = try retry(attempts: 3, task: task)
    print(result)
} catch {
    print(error)
}
```
In this example, the `task` function might fail randomly. The `retry` function is called with `attempts` set to 3, and the `task` function is passed as the `task` parameter. If the task fails, the `retry` function will retry it up to 3 times before throwing an error. If the task succeeds, the `retry` function will return the result.

func retry<T>(attempts: Int, task: @escaping () throws -> T) throws -> T  {
    var result: T?
    for _ in 1...attempts {
        do {
            result = try task()
            break
        } catch {
            print("Error: \(error.localizedDescription)")
        }
    }
    if let result = result {
        return result
    } else {
        throw NSError(domain: "RetryError", code: 1, userInfo: [NSLocalizedDescriptionKey: "Task failed after \(attempts) attempts"])
    }
}

    } else {
        throw NSError(domain: "RetryError", code: 1, userInfo: [NSLocalizedDescriptionKey: "Task failed after \(attempts) attempts"])
    }
}
```
This function takes a `task` closure that performs the task to be retried, and an `attempts` integer that specifies the number of times the task should be retried before failing. The function returns the result of the task if it succeeds, or throws an error if the task fails after the specified number of attempts.

You can use this function like this:
```swift
let task = {
    // Your task code here
}

do {
    let result = try retry(attempts: 3, task: task)
    print(result)
} catch {
    print("Error: \(error.localizedDescription)")
}
```
This will retry the `task` closure up to 3 times before failing. If the task succeeds, the result will be printed. If the task fails, an error will be thrown.

func retry<T>(attempts: Int, task: @escaping () throws -> T) throws -> T  {
    var result: T?

        } catch {
            error = error
        }
    }

```
This function takes two parameters: `attempts`, which is the number of times the task should be retried, and `task`, which is the task to be retried. The function returns the result of the task if it succeeds, or throws an error if the task fails after all attempts have been exhausted.

Here's an example usage of the `retry` function:
```swift
func fetchData() throws -> String {
    // some code that might fail
    return "data"
}

do {
    let data = try retry(attempts: 3, task: fetchData)
    print(data)
} catch {
    print("Error: \(error)")
}
```
In this example, the `fetchData` function might fail, so we use the `retry` function to retry the task up to 3 times before giving up. If the task succeeds, the `data` variable will contain the result of the task. If the task fails after all attempts have been exhausted, the `catch` block will be executed and the error will be printed.

func retry<T>(attempts: Int, task: @escaping () throws -> T) throws -> T  {

This function takes a closure `task` that performs the task to be retried, and an integer `attempts` that specifies the number of times to retry the task before failing. The function returns the result of the task, or throws an error if the task fails after all attempts have been exhausted.

```swift
func downloadFile(url: URL) throws -> Data {
    return try retry(attempts: 3) {

```
In this example, the `downloadFile` function downloads a file from a URL, and uses the `retry` function to retry the download up to 3 times before failing. If the download fails after all attempts have been exhausted, the function throws an error.

```
This function takes two arguments:

* `attempts`: The number of times to retry the task.
* `task`: A closure that represents the task to be retried.

The function uses a `for` loop to iterate over the number of attempts, and within the loop, it uses a `do-catch` block to catch any errors that may occur during the task execution. If an error is caught, the function stores the error in a variable and continues to the next iteration.

If all attempts fail, the function throws the last error that was caught. If all attempts succeed, the function returns the result of the last attempt.

Here's an example usage of the `retry` function:
```swift
func fetchData() throws -> Data {
    // code to fetch data
}

do {
    let data = try retry(attempts: 3, task: fetchData)
    // use the data
} catch {
    print(error)
}
```
In this example, the `fetchData` function is the task that is retried. The `retry` function is called with `attempts` set to 3, which means that the task will be retried 3 times before failing. If all attempts succeed, the `retry` function returns the result of the last attempt. If any attempt fails, the `retry` function throws the error that was caught.

This code defines a `DIContainer` class that conforms to the `DIContainerProtocol` protocol. The `DIContainer` class has a private dictionary `factories` that maps object identifiers to factory closures. The `register` method adds a new factory closure to the dictionary, and the `resolve` method retrieves a factory closure from the dictionary and calls it to create an instance of the requested type.

The `DIContainer` class also has a `register` method that takes a type and a factory closure as arguments. The `register` method adds the factory closure to the dictionary with the type as the key.

The `resolve` method takes a type as an argument and returns an instance of the requested type if it is registered in the container. If the type is not registered, the method returns `nil`.

You can use the `DIContainer` class as follows:
```swift
let container = DIContainer()

container.register(MyType.self) {
    MyType()
}

let myType = container.resolve(MyType.self)
```
This code creates a `DIContainer` instance and registers a factory closure for the `MyType` type. The `resolve` method is then called to retrieve an instance of `MyType` from the container.

```
This code defines a `DIContainer` class that implements the `DIContainerProtocol`. The `DIContainer` class has a `factories` dictionary that maps type names to factory functions. The `register` method adds a new factory function to the `factories` dictionary, and the `resolve` method retrieves a factory function from the `factories` dictionary and calls it to create a new instance of the specified type.

You can use this `DIContainer` class to register and resolve dependencies in your application. For example:
```swift
let container = DIContainer()

// Register a factory function for a type
container.register(MyType.self) {
    MyType()
}

// Resolve an instance of the registered type
let myType = container.resolve(MyType.self)
```
Note that this is a very basic implementation of a dependency injection container, and you may want to add additional features such as support for named dependencies, scoped dependencies, and more advanced dependency resolution strategies.

```
This code defines a `DIContainerProtocol` that has two methods: `register` and `resolve`. The `register` method takes a type and a factory function as arguments, and the `resolve` method takes a type and returns an instance of that type if it has been registered with the container.

The `DIContainer` class implements the `DIContainerProtocol` and stores the registered factories in a dictionary. The `register` method adds the factory function to the dictionary, and the `resolve` method retrieves the factory function from the dictionary and calls it to create an instance of the requested type.

You can use this container to register dependencies and resolve them later in your code. For example:
```swift
let container = DIContainer()

container.register(MyService.self) {
    MyService()
}

let service = container.resolve(MyService.self)
```
In this example, `MyService` is a type that has been registered with the container, and the `resolve` method returns an instance of `MyService`.

This is a simple implementation of a dependency injection (DI) container in Swift. It uses a dictionary to store factories for different types, and provides methods for registering and resolving dependencies.

The `register` method takes a type and a factory function as arguments, and stores the factory in the dictionary. The `resolve` method takes a type and returns an instance of that type, if it is registered in the container.

Note that this implementation is not thread-safe, and should not be used in a multi-threaded environment.

This code defines a `StateMachineProtocol` that has a `state` property and a `trigger` method. It also defines a `StateMachine` class that implements the protocol and has a `transitions` dictionary to store the custom transitions between states.

The `StateMachine` class has an `init` method that takes a `state` parameter and initializes the `state` property to that value. It also has a `trigger` method that takes an `event` parameter and checks if there is a custom transition registered for the current state and the given event. If there is, it updates the `state` property to the next state.

The `registerTransition` method takes a `from` state, a `to` state, and an `event` parameter and adds a custom transition to the `transitions` dictionary.

This code defines a `StateMachine` class that conforms to the `StateMachineProtocol` protocol. The `StateMachine` class has a `state` property that stores the current state of the machine, and a `transitions` dictionary that maps states to events to states.

The `trigger` method is used to trigger an event and transition to the next state, if a transition is registered for the current state and event.

The `registerTransition` method is used to register a transition between two states, with an optional event. If the event is not provided, the transition is registered for all events.

The `StateMachine` class also conforms to the `Equatable` protocol, which allows it to be compared for equality.

Note that this is a basic implementation of a finite state machine, and there are many ways to improve it, such as adding error handling, logging, or adding support for multiple events.

This code defines a protocol `StateMachineProtocol` with two associated types: `State` and `Event`. The `StateMachine` class implements this protocol and provides a default implementation for the `trigger` method. The `registerTransition` method is used to register custom transitions between states.

The `StateMachine` class has a private property `state` that stores the current state, and a private property `transitions` that stores a dictionary of transitions between states. The `transitions` dictionary is keyed by the current state and the event that triggered the transition, and the value is the next state.

The `trigger` method is used to trigger a transition between states. It first checks if there is a transition registered for the current state and the event. If there is, it updates the `state` property to the next state. If there is no transition registered, it does nothing.

The `registerTransition` method is used to register a custom transition between states. It takes three parameters: the current state, the next state, and the event that triggered the transition. It adds an entry to the `transitions` dictionary for the current state and the event, with the next state as the value.

You can use this code to create a state machine with custom transitions between states. For example:
```swift
let stateMachine = StateMachine<String, String>(state: "A")
stateMachine.registerTransition(from: "A", to: "B", event: "event1")
stateMachine.registerTransition(from: "B", to: "C", event: "event2")
stateMachine.trigger(event: "event1") // state is now "B"
stateMachine.trigger(event: "event2") // state is now "C"
```
In this example, the state machine starts in state "A" and has two custom transitions registered: from "A" to "B" on "event1", and from "B" to "C" on "event2". The `trigger` method is used to trigger the transitions, and the `state` property is updated accordingly.

This code defines a `StateMachine` class that conforms to the `StateMachineProtocol` protocol. The `StateMachine` class has a `state` property that stores the current state, and a `transitions` dictionary that maps states to events and their corresponding next states.

The `trigger` method is used to trigger an event and transition to the next state. If the event is not registered, the method does nothing.

The `registerTransition` method is used to register a custom transition between states. It takes three parameters: the current state, the next state, and the event that triggers the transition.

The `StateMachine` class also has a `init` method that initializes the state machine with a starting state.

Note that this is a basic implementation of a finite state machine, and it does not handle any errors or edge cases.

This code defines a `StateMachine` protocol that has a `state` property and a `trigger` method. It also has a `registerTransition` method that allows you to register custom transitions between states.

The `StateMachine` class implements the `StateMachineProtocol` and has a `state` property that stores the current state of the machine. It also has a `transitions` dictionary that stores the custom transitions between states.

The `trigger` method checks if there is a custom transition registered for the current state and event, and if so, it updates the state to the next state. If there is no custom transition, it does nothing.

The `registerTransition` method adds a custom transition to the `transitions` dictionary. It takes three parameters: `from`, `to`, and `event`. The `from` parameter is the current state, the `to` parameter is the next state, and the `event` parameter is the event that triggers the transition.

You can use this code to create a state machine with custom transitions between states. Here's an example:
```swift
let machine = StateMachine(state: "A")
machine.registerTransition(from: "A", to: "B", event: "event1")
machine.registerTransition(from: "B", to: "C", event: "event2")

machine.trigger(event: "event1") // state is now "B"
machine.trigger(event: "event2") // state is now "C"
```
In this example, we create a state machine with three states: "A", "B", and "C". We register two custom transitions: from "A" to "B" when "event1" is triggered, and from "B" to "C" when "event2" is triggered. We then trigger the "event1" event, which updates the state to "B", and then trigger the "event2" event, which updates the state to "C".

The `trigger` method takes an `event` as an argument and checks if there is a transition registered for the current state and the given event. If there is a transition, it updates the `state` property to the next state.

The `registerTransition` method takes a `from` state, a `to` state, and an `event` as arguments, and adds a transition to the `transitions` dictionary.

Note that the `State` and `Event` types are generic parameters that can be any type that conforms to the `Hashable` protocol. This allows the `StateMachine` class to be used with any type of state and event.

This code defines a `StateMachine` protocol that has two associated types: `State` and `Event`. The `StateMachine` class conforms to this protocol and implements the `trigger` and `registerTransition` methods.

The `StateMachine` class has a `state` property that stores the current state of the machine, and a `transitions` dictionary that maps each state to a dictionary of events to states. The `transitions` dictionary is used to store the custom transitions between states.

The `trigger` method takes an `event` as an argument and checks if there is a transition from the current state to a new state for that event. If there is a transition, the `state` property is updated to the new state.

The `registerTransition` method takes a `from` state, a `to` state, and an `event` as arguments, and adds a transition from the `from` state to the `to` state for that `event` to the `transitions` dictionary.

You can use this `StateMachine` class to create a finite state machine with custom transitions between states. For example:
```swift
let machine = StateMachine(state: "A")
machine.registerTransition(from: "A", to: "B", event: "event1")
machine.registerTransition(from: "B", to: "C", event: "event2")

machine.trigger(event: "event1") // state is now "B"
machine.trigger(event: "event2") // state is now "C"
```
This code creates a `StateMachine` with three states: "A", "B", and "C". It registers two transitions: from "A" to "B" when "event1" is triggered, and from "B" to "C" when "event2" is triggered. It then triggers the "event1" event, which moves the state machine from "A" to "B", and then triggers the "event2" event, which moves the state machine from "B" to "C".

This code defines a `StateMachine` class that has a `state` property and a `trigger` method. The `trigger` method takes an `event` parameter and triggers a transition to a new state based on the registered transitions. The `registerTransition` method allows you to register custom transitions between states.

The `StateMachine` class also has an `associatedtype` for the `State` and `Event` types, which allows you to define the types of states and events that the state machine can handle.

You can create an instance of the `StateMachine` class and register transitions between states using the `registerTransition` method. You can then trigger transitions by calling the `trigger` method with the appropriate event.

```
This code defines a `StackProtocol` protocol that has two methods: `push` and `pop`. The `push` method takes an element of type `Element` and adds it to the stack, while the `pop` method removes and returns the top element from the stack.

The `Stack` class is a generic class that conforms to the `StackProtocol` protocol. It has a private array property called `elements` that stores the elements of the stack. The `push` method adds an element to the end of the array, and the `pop` method removes and returns the last element from the array.

Note that the `Element` type must conform to the `Equatable` protocol, which allows the `pop` method to compare elements for equality.

protocol StackProtocol {
    associatedtype Element
    init()
    func push(_ element: Element)
    func pop() -> Element?
}

class Stack<  Element>: StackProtocol {
    private var elements: [Element] = []

    init() {}

    func push(_ element: Element) {
        elements.append(element)
    }

    func pop() -> Element? {
        guard !elements.isEmpty else { return nil }
        return elements.removeLast()
    }

class Stack<  Element>: StackProtocol {

}
```
This code defines a `StackProtocol` protocol that has two methods: `push` and `pop`. The `push` method takes an element of type `Element` and adds it to the stack, while the `pop` method removes and returns the top element from the stack.

The `Stack` class is a generic implementation of the `StackProtocol` protocol. It has a private `elements` array that stores the elements of the stack, and it implements the `push` and `pop` methods by adding and removing elements from the array.

You can use this code to create a stack of any type of element you want, like this:
```swift
let stack = Stack<Int>()
stack.push(1)
stack.push(2)
stack.push(3)

print(stack.pop()) // prints 3
print(stack.pop()) // prints 2
print(stack.pop()) // prints 1
```
This code creates a stack of integers, pushes three elements onto the stack, and then pops them off the stack and prints them.

    associatedtype Element
    init()
    func push(_ element: Element)
    func pop() -> Element?

This code defines a `StackProtocol` that has two functions: `push` and `pop`. The `push` function takes an element of type `Element` and adds it to the top of the stack, while the `pop` function removes and returns the element at the top of the stack.

The `Stack` class implements the `StackProtocol` and provides a concrete implementation of the `push` and `pop` functions. It uses an array to store the elements of the stack.

You can use this code to create a stack of any type of element, for example:
```swift
let stack = Stack<Int>()
stack.push(1)
stack.push(2)
stack.push(3)

print(stack.pop()) // prints 3
print(stack.pop()) // prints 2
print(stack.pop()) // prints 1
print(stack.pop()) // prints nil
```

protocol StackProtocol {
    associatedtype Element
    init()
    func push(_ element: Element)
    func pop() -> Element?
}

class Stack<  Element>: StackProtocol {
    private var elements: [Element] = []

    init() {}

    func push(_ element: Element) {
        elements.append(element)
    }

    func pop() -> Element? {
        guard !elements.isEmpty else { return nil }
        return elements.removeLast()
    }
}

This code defines a `StackProtocol` protocol that has two methods: `push` and `pop`. The `push` method takes an element of type `Element` and adds it to the stack, while the `pop` method removes and returns the top element from the stack.

The `Stack` class is a generic class that conforms to the `StackProtocol` protocol. It has a private `elements` array that stores the elements of the stack, and it implements the `push` and `pop` methods by adding and removing elements from the `elements` array.

The `Element` type parameter is constrained to be `Equatable`, which means that the elements of the stack must be comparable using the `==` operator. This is necessary for the `pop` method to be able to remove the top element from the stack.

You can use this code to create a stack of any type of element that is `Equatable`, like this:
```swift
let stack = Stack<Int>()
stack.push(1)
stack.push(2)
stack.push(3)
print(stack.pop()) // prints 3
print(stack.pop()) // prints 2
print(stack.pop()) // prints 1
print(stack.pop()) // prints nil
```
This code creates a stack of integers, pushes three elements onto the stack, and then pops them off one by one. The `pop` method returns `nil` when the stack is empty.

protocol StackProtocol {
    associatedtype Element
    init()
    func push(_ element: Element)

This code defines a `StackProtocol` protocol that has an associated type `Element` and three methods: `init()`, `push(_:)`, and `pop()`. The `init()` method initializes a new stack, the `push(_:)` method adds an element to the top of the stack, and the `pop()` method removes and returns the element at the top of the stack.

The `Stack` class implements the `StackProtocol` protocol and provides a generic implementation of the stack data structure. The `elements` property is a private array that stores the elements of the stack, and the `push(_:)` and `pop()` methods manipulate this array to implement the stack operations.
