This code defines a `calculate` function that takes a string input and returns a `Double` result. It uses a recursive descent parser to evaluate the expression. The `tokenize` function splits the input string into tokens, which are then processed by the parser functions `parseExpression`, `parseTerm`, and `parseFactor`. The parser handles the order of operations and parentheses correctly. If the input is invalid, it throws a `CalculateError.invalidInput` error.var tokens = tokenize(string) // variable 'tokens' was never mutated; consider changing to 'let' constantenum CalculateError: Error {
case invalidInput

}Here's a simple implementation of a dependency injection (DI) container in Swift:
```swift
protocol DIContainerProtocol {
func register<T>(_ type: T.Type, factory: @escaping () -> T)
func resolve<T>(_ type: T.Type) -> T?
}
class DIContainer: DIContainerProtocol {
private var factories: [String: () -> Any] = [:]
func register<T>(_ type: T.Type, factory: @escaping () -> T) {
let key = String(describing: type)
factories[key] = factory
}
func resolve<T>(_ type: T.Type) -> T? {
let key = String(describing: type)
guard let factory = factories[key] else {
return nil
}
return factory() as? T
}
}
```
This `DIContainer` class implements the `DIContainerProtocol`. It uses a dictionary to store factory closures for different types, identified by their type names as strings. The `register` method allows you to register a factory closure for a specific type, and the `resolve` method retrieves an instance of the requested type by invoking the corresponding factory closure.protocol DIContainerProtocol {
func register<T>(_ type: T.Type, factory: @escaping () -> T)
