Dependecy registration

Single dependency

diContainer
    .register(XMLDecodable.self) { _ in
        return XMLDecoder()
    }
    .asSingleton()

Lazy single dependency

diContainer
    .register(ErrorLoggable.self) { _ in
        return LocalErrorLogger()
    }
    .asLazySingleton()

Weak dependency

diContainer
    .register(XMLValidator.self) { _ in
        return XMLValidator()
    }
    .asWeak()

Dependency resolvation

Local DI container

let diContainer = DIContainer()

diContainer
    .register(XMLDecodable.self) { _ in
        return XMLDecoder()
    }
    .asLazySingleton()

let decoder1: XMLDecodable = diContainer.resolve()
// or
@Resolve(container: diContainer) var decoder2: XMLDecodable

Global DI container

GlobalDI
    .container
    .register(XMLDecodable.self) { _ in
        return XMLDecoder()
    }
    .asLazySingleton()

let decoder1: XMLDecodable = GlobalDI.container.resolve()
// or
@Resolve var decoder2: XMLDecodable
