swiftui navigation state-management swift

I'm encountering an issue with `NavigationLink` in SwiftUI where the navigated view does not preserve its state after returning to it from another view. I have a simple list where each item navigates to a detail view, but when I go back and navigate again, the state seems to reset. Here’s a simplified version of my code: ```swift struct ContentView: View { @State private var selectedItem: Item? var items: [Item] = [/* array of items */] var body: some View { NavigationView { List(items) { item in NavigationLink(destination: DetailView(item: item, isActive: $selectedItem)) { Text(item.name) } } .navigationTitle("Items") } } } struct DetailView: View { var item: Item @Binding var isActive: Item? var body: some View { VStack { Text(item.name) // Other UI elements and state Button("Go Back") { isActive = nil } } .onAppear { print("Detail view appeared for: \(item.name)") } } } ``` The `DetailView` should show the current item, but when I return to the `ContentView` and navigate back, the state of `DetailView` (like text inputs or toggles I've set) is lost. I've tried using `@StateObject` and `@ObservedObject` to manage the state, but it doesn't seem to help. I also attempted to use the `.navigationBarBackButtonHidden(true)` modifier to customize the back navigation, but it didn’t resolve the state issue. The console logs indicate that `onAppear` is being called each time, suggesting that the view is being recreated. How can I maintain the state of `DetailView` when re-navigating without resetting it? Any suggestions would be greatly appreciated!
