This function converts the input string to data, then tries to convert the data to a JSON object. If the input string cannot be converted to data, or if the data cannot be converted to a JSON object, it throws an error. If any other error occurs during the conversion process, it throws that error.typealias JSON = [String: Any]

This function takes a string as input and attempts to convert it into a JSON object. If the string cannot be converted into data or the data cannot be converted into a JSON object, it throws a `ParsingError.invalidInput` error. If any other error occurs during the JSON serialization, it throws a `ParsingError.internalError` error with the underlying error.typealias JSON = [String: Any]
enum ParsingError: Error {
case invalidInput
case internalError(Error)
}
import Foundation
func parse(string: String) throws -> JSON {
guard let data = string.data(using: .utf8) else {

}
do {

return json
} else {
throw ParsingError.invalidInput
}
} catch let error {
throw ParsingError.internalError(error)
}
}Here is a simple JSON parser using Swift's built-in JSONSerialization class:
```swift
import Foundation
typealias JSON = [String: Any]
enum ParsingError: Error {
case invalidInput
case internalError(Error)
}
func parse(string: String) throws -> JSON {
guard let data = string.data(using: .utf8) else {
throw ParsingError.invalidInput
}
do {
if let json = try JSONSerialization.jsonObject(with: data, options: []) as? JSON {
return json
} else {
throw ParsingError.invalidInput
}
} catch let error {
throw ParsingError.internalError(error)
}
}
```
This function first converts the input string to Data. If this fails, it throws a ParsingError.invalidInput error. It then attempts to convert this data to a JSON object. If this fails, it throws the underlying error wrapped in a ParsingError.internalError. If the resulting object is not a dictionary with String keys and Any values, it throws a ParsingError.invalidInput error. If all these steps succeed, it returns the resulting JSON object.typealias JSON = [String: Any]

This function `parse(string: String)` takes a JSON string as input and tries to convert it into a `JSON` object. If the string cannot be converted to `Data` or the `Data` cannot be converted to `JSON`, it throws a `ParsingError.invalidInput` error. If there is any other error during the parsing process, it throws a `ParsingError.internalError` error with the original error attached.typealias JSON = [String: Any]

This code defines a `generate` function that takes an `HTMLNode` and returns a `String`. It uses a `switch` statement to handle the different cases of the `HTMLNode` enum. If the node is a `.text` node, it escapes the content and returns it. If the node is an `.element` node, it renders the attributes and children, and returns a string in the format of an HTML tag.
The `render` function takes a dictionary of attributes and returns a string of the attributes in the format of HTML attributes.
The `escape` function takes a string and replaces certain characters with their corresponding HTML entities. This is necessary to prevent HTML injection attacks.indirect enum HTMLNode {
case text(_ content: String)
case element(_ name: String, attributes: [String : String] = [:], children: [Self] = [])

This code defines a `generate` function that takes an `HTMLNode` and returns a `String`. It uses a switch statement to handle the different cases of the `HTMLNode` enum. If the node is a text node, it escapes the content and returns it. If the node is an element node, it generates the opening and closing tags, and recursively generates the content for any child nodes.
The `generateAttributes` function takes a dictionary of attribute names and values, and generates a string of HTML attributes.
The `escape` function replaces certain characters in a string with their corresponding HTML entities to prevent injection attacks.indirect enum HTMLNode {

This code defines a `generate` function that takes an `HTMLNode` and returns a `String`. It uses a `switch` statement to handle the different cases of the `HTMLNode` enum. If the node is a `.text` node, it simply escapes the content and returns it. If the node is an `.element` node, it generates a string for the element's name, attributes, and children, and then combines them into a single string.
The `escape` function is used to replace certain characters in a string with their corresponding HTML entities. This is necessary to prevent injection attacks and to ensure that the generated HTML is well-formed.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):
let attrs = attributes.map { key, value in
"\(key)=\"\(value)\""
}.joined(separator: " ")
let childrenHTML = children.map(generate).joined()
return "<\(name) \(attrs)>\(childrenHTML)</\(name)>"
}

This function uses a switch statement to handle the different cases of the `HTMLNode` enum. If the node is a text node, it simply returns the content of the text. If the node is an element, it generates the opening and closing tags, the attributes, and the HTML for the children. The attributes are generated by mapping over the attributes dictionary and joining the resulting strings with a space. The children's HTML is generated by mapping the `generate` function over the children array and joining the resulting strings.indirect enum HTMLNode {
case text(_ content: String)
case element(_ name: String, attributes: [String : String] = [:], children: [Self] = [])

This code defines a `generate` function that takes an `HTMLNode` and returns a `String`. It uses a `switch` statement to handle the two cases of the `HTMLNode` enum: `.text` and `.element`.
In the `.text` case, it simply escapes the content and returns it.
In the `.element` case, it first maps the attributes dictionary to an array of strings in the format `key="value"`, joins them with a space separator, and assigns the result to `renderedAttributes`. Then it maps the children array to an array of strings by recursively calling `generate` on each child, joins them, and assigns the result to `renderedChildren`. Finally, it returns a string in the format `<name attributes>children</name>`.
The `escape` function takes a `String` and returns a new `String` where the characters `<`, `>`, `&`, and `"` are replaced with their corresponding HTML entities. It does this by iterating over the characters of the input string, appending the escaped version of each character to `result`, and returning `result`.indirect enum HTMLNode {

This code defines a function `generate` that takes an `HTMLNode` and returns a `String`. The `HTMLNode` enum has two cases: `text` and `element`. The `text` case represents a text node in the HTML tree, and the `element` case represents an HTML element with a name, a dictionary of attributes, and an array of child nodes.
The `generate` function uses a switch statement to handle the two cases. If the node is a `text` node, it simply returns the content of the text node. If the node is an `element` node, it first maps over the attributes dictionary to create an array of strings in the form "key=value", then joins these strings with a space to create the string of attributes. It then maps over the array of child nodes, recursively calling `generate` on each child, and joins the resulting strings. Finally, it returns a string representing the HTML element, with the name, attributes, and child nodes.indirect enum HTMLNode {

```swift
func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U {

if let cachedValue = cache[value] {

} else {
let result = function(value)
cache[value] = result
return result
}
}
}
```
This function takes a function as an argument and returns a new function that caches the results of the original function. The cache is a dictionary that maps input values to their corresponding output values. When the returned function is called with a certain input, it first checks if the result for that input is already in the cache. If it is, it returns the cached result. If it isn't, it calculates the result using the original function, stores it in the cache, and then returns it.func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U {
var cache = [T: U]()
return { (value: T) -> U in
if let cachedValue = cache[value] {

} else {
let result = function(value)
cache[value] = result
return result

```
This function takes another function as an argument and returns a new function that caches the results of the original function. The cache is a dictionary that maps input values to output values. When the returned function is called with an input value, it first checks if the result is already in the cache. If it is, it returns the cached result. If it's not, it calls the original function to compute the result, stores it in the cache, and returns it.func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U {
var cache = [T: U]()
return { (value: T) -> U in

}
}
}
```
This function takes a function as an argument and returns a new function that caches the results of the original function. The cache is a dictionary that maps inputs to outputs. If the function is called with an input that is already in the cache, the function returns the cached output instead of calling the original function. If the input is not in the cache, the function calls the original function, stores the result in the cache, and returns the result.func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U {
var cache = [T: U]()
return { (input: T) -> U in
if let cachedResult = cache[input] {
return cachedResult
} else {
let result = function(input)
cache[input] = result
return result
}

This function takes another function as an argument and returns a new function that behaves exactly like the original function but also caches its results. The type `T` must conform to the `Hashable` protocol because it is used as a key in a dictionary. The type `U` is the return type of the function. The function uses a local variable `cache` to store the results of the function calls. If the function is called with the same arguments again, it first checks if the result is already in the cache. If it is, it returns the cached result. If it's not, it calculates the result, stores it in the cache, and then returns it.func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U {
var cache = [T: U]()
return { (value: T) -> U in

This function takes a function as an argument and returns a new function that caches the results of the original function. The cache is a dictionary that maps input values to their corresponding output values. When the returned function is called with a particular input, it first checks if the result for that input is already in the cache. If it is, it returns the cached result. If it's not, it calls the original function to compute the result, stores the result in the cache, and then returns the result.func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U {

This function takes a function as input and returns a new function that caches the results of the input function. The returned function behaves exactly like the input function, but it stores the results of previous computations in a cache, so that if the function is called again with the same arguments, it can return the cached result instead of recomputing the result. This can significantly speed up computations for functions that are expensive to compute and are called multiple times with the same arguments.func memoize<T: Hashable, U>(_ function: @escaping (T) -> U) -> (T) -> U {
