Weather application provider.
Handle user actions to fill search bar results and use WeatherProvider to check forecast.
### Response:
```swift
protocol WeatherProvider {
    func forecast(for city: String) throws -> String
}

enum UserAction {
    case keyboardCharacterSelect(Character)
    case keyboardDeleteBackwards
    case searchButtonPress
}

enum ApplicationFeedback: Equatable {
    case success(city: String, forecast: String)
    case failure(city: String)
}

protocol WeatherApplicationDependencies {
    init(provider: WeatherProvider)
}

protocol WeatherApplicationInteractions {
    func handle(action: UserAction) -> ApplicationFeedback?
}

typealias WeatherApplicationProtocol = WeatherApplicationDependencies & WeatherApplicationInteractions

class WeatherApplication: WeatherApplicationProtocol {
    private var searchString = ""
    private var provider: WeatherProvider
    
    init(provider: WeatherProvider) {
