7. Strategy
8. Strategy Pattern
9. Strategy Pattern // MARK: - Interface public protocol TodoRepository { func get(_ handler: @escaping (Result<[TodoEntity]>) -> Void) } // MARK: - Implementation final class TodoRepositoryImpl: TodoRepository { private let dataStore: TodoDataStore public init(dataStore: TodoDataStore) { self.dataStore = dataStore } func get(_ handler: @escaping (Result<[TodoEntity]>) -> Void) { dataStore.get(with: ["filter": "all"]).onSuccess { entities in let result = Result<[TodoEntity]>.success(entities) handler(result) }.onFailure { error in let result = Result<[TodoEntity]>.failure(error) handler(result) } } }
10. Strategy Pattern typealias TodoListComplitionHandler = ([TodoModel]?) -> Void // MARK: - Interface protocol TodoListUseCase { func fetchTodos(_ complite: TodoListComplitionHandler?) } // MARK: - Implementation struct TodoListUseCaseImpl: TodoListUseCase { private let todoRepository: TodoRepository public init(todoRepository: TodoRepository) { self.todoRepository = todoRepository } public func fetchTodos(_ compliton: TodoListComplitionHandler?) { todoRepository.get { result in switch result { case .success(let value): let todoModels = try! TodoTranslator().translate(value) compliton?(todoModels) case .failure(let error): print(error) compliton?(nil) } } } }
