The function uses the `Hashable` protocol to ensure that the input values can be used as dictionary keys. The `cache` dictionary is a dictionary of type `[T: U]`, where `T` is the type of the input values and `U` is the type of the output values.

```
This function takes two parameters: `attempts` and `task`. `attempts` is the number of times the task should be retried before failing. `task` is a closure that represents the task to be retried.
The function first initializes a variable `currentAttempt` to 0. It then enters a loop that runs until `currentAttempt` is equal to `attempts`.
Inside the loop, the function tries to execute the `task` closure. If the `task` throws an error, the function catches the error and increments `currentAttempt`. If the `task` does not throw an error, the function returns the result of the `task`.
If the `task` throws an error and `currentAttempt` is equal to `attempts`, the function rethrows the error.
Here's an example of how you can use the `retry` function:
```swift
let result = retry(attempts: 3) {
// This is the task that should be retried
print("Hello, world!")
}

```
This code will print "Hello, world!" three times, and then print the result of the `task`.

```
This is a simple dependency injection (DI) container that allows you to register and resolve dependencies.
The `DIContainer` class has two methods: `register` and `resolve`.
The `register` method takes a type and a factory function that creates an instance of that type. The factory function is stored in a dictionary with the type as the key.
The `resolve` method takes a type and returns an instance of that type if it has been registered. If the type has not been registered, it returns `nil`.
You can use this container to register and resolve dependencies in your application. For example:
```swift
let container = DIContainer()
// Register a factory function for the `UserService` type
container.register(UserService.self) {
return UserService()
}
// Resolve an instance of `UserService`
let userService = container.resolve(UserService.self)
```
This is just a simple example of how you can use a DI container in Swift. You can add more features and functionality to the container as needed.protocol DIContainerProtocol {

The `DIContainer` class has two methods: `register` and `resolve`.
The `register` method takes a type and a factory function that creates an instance of that type. The factory function is stored in a dictionary with the type as the key.
The `resolve` method takes a type and returns an instance of that type if it has been registered. If the type has not been registered, it returns `nil`.
You can use this container to register and resolve dependencies in your application. For example:
```swift
let container = DIContainer()
// Register a factory function for the `UserService` type
container.register(UserService.self) {
return UserService()
}
// Resolve an instance of `UserService`
let userService = container.resolve(UserService.self)
```
This is just a simple example of how you can use a DI container in Swift. You can add more features and functionality to the container as needed.protocol DIContainerProtocol {
func register<T>(_ type: T.Type, factory: @escaping () -> T)
func resolve<T>(_ type: T.Type) -> T?

This code defines a protocol `StateMachineProtocol` that defines the basic functionality of a state machine. It has two associated types: `State` and `Event`. The `StateMachine` class implements this protocol and has a `state` property that stores the current state of the machine, and a `transitions` dictionary that stores the possible transitions between states.
The `init` method initializes the state machine with a given initial state. The `trigger` method takes an event and updates the state of the machine according to the registered transitions. The `registerTransition` method registers a new transition between two states for a given event.
This code allows you to create a state machine with custom transitions between states, and trigger events to update the state of the machine.private var state: State // property 'state' must be declared internal because it matches a requirement in internal protocol 'StateMachineProtocol'init(state: State) { // initializer requirement 'init(state:)' can only be satisfied by a 'required' initializer in non-final class 'StateMachine<State, Event>'protocol StateMachineProtocol {

The `timeInterval` property represents the time interval in which the maximum number of requests can be made.
The `allowRequest()` method is the main method of the class, which determines if a new request can be made within the defined limits. The method first checks if the `lastRequestTime` property is set. If it is not set, it means that this is the first request, and the method allows it. If it is set, the method checks if the time since the last request is less than the `timeInterval`. If it is, the method returns `false`, indicating that the request cannot be made. If the time since the last request is greater than the `timeInterval`, the method sets the `lastRequestTime` property to the current time and returns `true`, indicating that the request can be made.init(maxRequests: Int, timeInterval: TimeInterval) { // initializer requirement 'init(maxRequests:timeInterval:)' can only be satisfied by a 'required' initializer in non-final class 'RateLimiter'Thread.sleep(forTimeInterval: 1) // class method 'sleep' is unavailable from asynchronous contexts; Use Task.sleep(until:clock:) instead.; this is an error in Swift 6protocol RateLimiterProtocol {

This code defines a `PipelineProtocol` that has an associated type `Output` and a `pipe` method that takes a transformation function of type `(Output) -> U` and returns a new `Pipeline` instance with the transformed value. The `Pipeline` class is a concrete implementation of the `PipelineProtocol` that takes an initial value of type `Output` and provides a `pipe` method that applies the transformation function to the initial value and returns a new `Pipeline` instance with the transformed value. The `execute` method returns the final output of the pipeline.
The `extension PipelineProtocol` adds a default implementation of the `pipe` method that can be used to create a pipeline from any type that conforms to `PipelineProtocol`.
The code example demonstrates how to create a pipeline by chaining multiple transformations using the `pipe` method.

This is a generic observable property that notifies observers of value changes. It uses a protocol to define the type of the value and the observers. The property has a private `observers` dictionary that maps UUIDs to observer functions. The `subscribe` method adds a new observer to the dictionary, and the `unsubscribe` method removes an observer from the dictionary. The `notifyObservers` method calls the observer functions for all observers in the dictionary. The `setValue` method sets the value of the property and notifies all observers.observable.value = 10 // 'value' is inaccessible due to 'private' protection levelobservable.value = 20 // 'value' is inaccessible due to 'private' protection levelobservable.value = 30 // 'value' is inaccessible due to 'private' protection levelprotocol ObservablePropertyProtocol {

This is a generic observable property that notifies observers of value changes. It uses a protocol to define the type of the value and the observers. The property has a private `observers` dictionary that maps UUIDs to observer functions. The `subscribe` method adds a new observer to the dictionary, and the `unsubscribe` method removes an observer from the dictionary.

```
This code defines a `WeatherProvider` protocol that provides a `forecast(for:)` method that takes a `city` parameter and returns a `String` representing the forecast for that city.
The `UserAction` enum defines the different actions that the user can take in the weather application, such as selecting a character on the keyboard, deleting a character, or pressing the search button.
The `ApplicationFeedback` enum defines the different types of feedback that the application can provide to the user, such as a success message or a failure message.
The `WeatherApplicationDependencies` protocol defines the dependencies that the `WeatherApplication` class needs to function, such as a `WeatherProvider` instance.
The `WeatherApplicationInteractions` protocol defines the methods that the `WeatherApplication` class can use to interact with the user, such as handling user actions.
The `WeatherApplicationProtocol` typealias combines the `WeatherApplicationDependencies` and `WeatherApplicationInteractions` protocols to create a single protocol that defines both the dependencies and interactions of the `WeatherApplication` class.
The `WeatherApplication` class implements the `WeatherApplicationProtocol` protocol and provides an implementation for the `handle(action:)` method that takes a `UserAction` parameter and returns an `ApplicationFeedback` value based on the user action. The `WeatherApplication` class also initializes with a `WeatherProvider` instance and stores it as a property.init(provider: WeatherProvider) { // initializer requirement 'init(provider:)' can only be satisfied by a 'required' initializer in non-final class 'WeatherApplication'return .success(city: character, forecast: try! provider.forecast(for: character)) // cannot convert value of type 'Character' to expected argument type 'String'return .success(city: character, forecast: try! provider.forecast(for: character)) // cannot convert value of type 'Character' to expected argument type 'String'protocol WeatherProvider {

```
This code defines a `WeatherProvider` protocol that provides a `forecast(for:)` method that takes a `city` parameter and returns a `String` representing the forecast for that city.
The `UserAction` enum defines the different actions that the user can take in the weather application, such as selecting a character on the keyboard, deleting a character, or pressing the search button.
The `ApplicationFeedback` enum defines the different types of feedback that the application can provide to the user, such as a success message or a failure message.
The `WeatherApplicationDependencies` protocol defines the dependencies that the `WeatherApplication` class needs to function, such as a `WeatherProvider` instance.
The `WeatherApplicationInteractions` protocol defines the methods that the `WeatherApplication` class can use to interact with the user, such as handling user actions.
The `WeatherApplicationProtocol` typealias combines the `WeatherApplicationDependencies` and `WeatherApplicationInteractions` protocols to create a single protocol that defines both the dependencies and interactions of the `WeatherApplication` class.
The `WeatherApplication` class implements the `WeatherApplicationProtocol` protocol and provides an implementation for the `handle(action:)` method that takes a `UserAction` parameter and returns an `ApplicationFeedback` value based on the user action. The `WeatherApplication` class also initializes with a `WeatherProvider` instance and stores it as a property.init(provider: WeatherProvider) { // initializer requirement 'init(provider:)' can only be satisfied by a 'required' initializer in non-final class 'WeatherApplication'return .success(city: character, forecast: try! provider.forecast(for: character)) // cannot convert value of type 'Character' to expected argument type 'String'return .success(city: character, forecast: try! provider.forecast(for: character)) // cannot convert value of type 'Character' to expected argument type 'String'protocol BankAccountProtocol {
