swiftui navigationlink iphone ios17 Swift

I'm collaborating on a project where I'm working with a frustrating scenario with `NavigationLink` in SwiftUI on an iPhone 15 running iOS 17... The expected behavior is that tapping on a `NavigationLink` should navigate to a detail view, but it seems that the view is not updating correctly after selection. Here’s a simplified example of my code: ```swift struct ContentView: View { @State private var selectedItem: Item? = nil let items: [Item] = [Item(name: "Item 1"), Item(name: "Item 2")] var body: some View { NavigationView { List(items) { item in NavigationLink(destination: DetailView(item: item), tag: item, selection: $selectedItem) { Text(item.name) } } .onAppear { self.selectedItem = nil // Reset selection } } } } struct DetailView: View { let item: Item var body: some View { Text("Detail for \(item.name)") } } ``` I've confirmed that the `Item` struct conforms to `Identifiable`. I also have set `selectedItem` to `nil` in `onAppear`, hoping to reset any previous selections. However, when I tap on a `NavigationLink`, the detail view does not load correctly; it sometimes shows the previous detail view instead of the new one. I've tried debugging with print statements to check the state of `selectedItem`, but it seems to be updating correctly. I'm getting no behavior messages in the console, which adds to my confusion. I've also tried moving the `NavigationView` to a separate view and utilizing `@Binding` for `selectedItem`, but that did not yield any improvements. Is there a known scenario with `NavigationLink` and state management in SwiftUI on iOS 17? Any help or insights would be greatly appreciated! The stack includes Swift and several other technologies. The project is a mobile app built with Swift. Thanks for taking the time to read this!
