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")
]
),
