Destination with empty associated value case

[nmalevich]

I want to present photoPicker and push other my screen from one view.

Parent feature:

@Reducer
public struct ParentFeature {
    public init() {}

    @ObservableState
    public struct State {
        Presents var destination: Destination.State?
        ...
    }

    public enum Action {
        case destination(PresentationAction<Destination.Action>)
        ...
    }

    public var body: some ReducerOf<Self> {
       Reduce { state, action in
           ...
       }
       .ifLet(\.$destination, action: \.destination)
    }
}

extension ParentFeature {
    @Reducer
    public enum Destination {
        case child(ChildFeature)
        case photoPicker
    }
}

Parent view:

public struct ParentView: View {
    @Perception.Bindable public var store: StoreOf<ParentFeature>
    
    public init(store: StoreOf<ParentFeature>) {
        self.store = store
    }
    
    public var body: some View {
        WithPerceptionTracking {
            ...
            .navigationDestinationWrapper(
                item: $store.scope(state: \.destination?.crop, action: \.destination.crop)
            ) { store in
                CropView(store: store)
            }
            .sheet(
                item: $store.scope(state: \.destination?.photoPicker, action: \.photoPicker) \\ Building error
            ) { store in
                PhotoPickerView()
            }
        }
    }
}

Yes, of course I can do it by Binding property in my state like isPhotoPickerVisible. But for me will be better if you can help me with that. Thank you

Hi @nmalevich, if you are on the newest version of TCA (1.9.3), then you should be doing this:

.sheet(
  item: $store.scope(state: \.destination?.photoPicker, action: \.destination.photoPicker)
) { store in
  …
}
