SwiftUI NavigationLink Not Retaining State When Pushing Views on iOS 17
Could someone explain I'm migrating some code and I tried several approaches but none seem to work..... I'm encountering a frustrating issue with a SwiftUI app on iOS 17 where the state of my views is not being retained when navigating using `NavigationLink`. Specifically, I have a list of items, and when I tap on an item, it navigates to a detail view. However, if I go back to the list and then tap on another item, the state of the previous detail view is lost and resets to its initial state. Here’s a simplified version of my code: ```swift struct ContentView: View { @State private var selectedItem: Item? @State private var items: [Item] = [Item(name: "Item 1"), Item(name: "Item 2")] var body: some View { NavigationView { List(items) { item in NavigationLink(destination: DetailView(item: item, selectedItem: $selectedItem)) { Text(item.name) } } .navigationTitle("Items") } } } struct DetailView: View { var item: Item @Binding var selectedItem: Item? var body: some View { VStack { Text(item.name) Button("Select this item") { selectedItem = item } } .onAppear { // Potentially load data related to selectedItem print("Selected item: \(String(describing: selectedItem))") } } } ``` I've tried using an `@EnvironmentObject` to manage shared state but it didn't help retain the state when navigating back and forth. The only thing I can think of is that when I navigate back, the `DetailView` is being recreated, thus losing its previous state. I've also checked the lifecycle events using `.onAppear` and `.onDisappear`, but the issue persists. What am I missing here? How can I ensure that the state in `DetailView` is maintained when navigating back and forth between items? Any insights would be appreciated! I'm working on a service that needs to handle this. Thanks for any help you can provide!
