swiftui navigationlink state-management Swift

I've been struggling with this for a few days now and could really use some help... I'm integrating two systems and I've been struggling with this for a few days now and could really use some help. I am experiencing an issue with `NavigationLink` in my SwiftUI application. I have a view that should update when a state variable changes, but it seems the UI does not reflect this change unless I manually navigate back and forth. I am using SwiftUI with iOS 16. Here's a simplified version of my code: ```swift struct ContentView: View { @State private var isDetailViewActive = false @State private var itemCount = 0 var body: some View { NavigationView { VStack { Text("Item Count: \(itemCount)") Button("Add Item") { itemCount += 1 } NavigationLink(destination: DetailView(itemCount: itemCount), isActive: $isDetailViewActive) { Text("Go to Detail") } } } } } struct DetailView: View { var itemCount: Int var body: some View { Text("Detail view count: \(itemCount)") } } ``` When I click "Add Item", the count increases, but when I navigate to the `DetailView`, it still shows the old count. I've tried using `@Binding` and `ObservableObject`, but the issue persists. I've also added a `.onAppear` modifier on the `DetailView`, but it doesn't seem to help either. I am getting the following warning in Xcode logs when I navigate: `Unbalanced calls to begin/end appearance transitions for <DetailView: ...>`. Any suggestions on how to ensure that the `DetailView` reflects the latest `itemCount` when I navigate to it? Am I missing something fundamental about state management in SwiftUI? My development environment is Linux. How would you solve this? My development environment is Linux. What's the correct way to implement this?
