swiftui – Replace atmosphere object on listRow click on earlier than navigation

If you need to help iOS 13-14 you should utilize .onAppear hooked up to the vacation spot.

If you need to help iOS 15 you should utilize .process hooked up to the vacation spot.

struct Retailer{
    var gadgets: [Task] = [.init(name: UUID().uuidString), .init(name: UUID().uuidString), .init(name: UUID().uuidString)]
    var chosen: Process?
    struct Process: Identifiable{
        let id: UUID = .init()
        let title: String
    }
}

@obtainable(iOS 15.0, *)
struct OnSelectView: View {
    @Surroundings (.colorScheme) var colorScheme:ColorScheme
    @Surroundings(.presentationMode) var presentationMode: Binding<PresentationMode>
    @State var retailer: Retailer = .init()
    var physique: some View {
        NavigationView{
            Checklist {
                ForEach(retailer.gadgets, id:.id) { taskObj in
                    NavigationLink(vacation spot:
                        detailView(taskObj)
                        //.onAppear{ //or
                        .process {
                            //do one thing right here
                            retailer.chosen = taskObj
                        }
                    ) {
                        Textual content(taskObj.title)
                    }
                }
            }
        }
    }
    
    @ViewBuilder func detailView (_ process: Retailer.Process) -> some View{
        VStack{
            Textual content(process.title)
            if let chosen = retailer.chosen{
                Textual content(chosen.title)
            }else{
                ProgressView()
            }
        }
    }
}

The choices above should not technically carry out earlier than navigation they’re carried out because the view “seems”.

If you need to help iOS 16 it’s best to use NavigationStack together with NavigationPath and navigationDestination.

@obtainable(iOS 16.0, *)
struct OnSelectView: View {
    @Surroundings (.colorScheme) var colorScheme:ColorScheme
    @Surroundings(.presentationMode) var presentationMode: Binding<PresentationMode>
    @State var retailer: Retailer = .init()
    @State var path: NavigationPath = .init()
    var physique: some View {
        NavigationStack(path: $path){
            Checklist {
                ForEach(retailer.gadgets, id:.id) { taskObj in
                    Button {
                        //Do one thing
                        retailer.chosen = taskObj
                        
                        path.append(taskObj)
                    } label: {
                        HStack{
                            Textual content(taskObj.title)
                            Spacer()
                            Picture(systemName: "chevron.ahead")
                                .foregroundColor(Shade(UIColor.placeholderText))
                        }
                    }.buttonStyle(.plain)
                }
            }.navigationDestination(for: Retailer.Process.self) { process in
                detailView(process)
            }
        }
    }
    
    @ViewBuilder func detailView (_ process: Retailer.Process) -> some View{
        VStack{
            Textual content(process.title)
            if let chosen = retailer.chosen{
                Textual content(chosen.title)
            }else{
                ProgressView()
            }
        }
    }
