A companion library to Point-Free's swift-composable-architecture.
In the current TCA, TaskResult was not Equatable compliant, so it must be written like this
public struct HogeFeature: Reducer { public struct State: Equatable {} public enum Action: Equatable { case onAppear case response(TaskResult<EquatableVoid>) } public func reduce(into state: inout State, action: Action) -> Effect<Action> { switch action { case .onAppear: return .run { send in await send( .response( TaskResult { try await asyncThrowsVoidFunc() return VoidSuccess() } ) ) } case .response(.success): // do something return .none case .response(.failure(let error)): // handle error return .none } } }it is not kind to create an VoidSuccess on user just to conform TaskResult to Equatable even though Void is already provided in Swift. So we extended TaskResult so that it could be written like this.
public struct HogeFeature: Reducer { public struct State: Equatable {} public enum Action: Equatable { case onAppear case response(TaskResult<VoidSuccess>) } public func reduce(into state: inout State, action: Action) -> Effect<Action> { switch action { case .onAppear: return .run { send in await send( .response( TaskResult { try await asyncThrowsVoidFunc() } ) ) } case .response(.success): // do something return .none case .response(.failure(let error)): // handle error return .none } } }In the dependencies section, add:
.package(url: "https://github.com/Ryu0118/swift-composable-architecture-extras", from: "1.0.0")In each module, add:
.target( name: "MyModule", dependencies: [ .product(name: "ComposableArchitectureExtras", package: "swift-composable-architecture-extras") ] ),
