swiftui ios navigationview state observables swift

I'm working with an scenario where the `NavigationView` in my SwiftUI app does not update the view when the state changes. This question arises when I use `@StateObject` to manage my observable model. I have a simple app built using SwiftUI targeting iOS 17. The expected behavior is that when the user taps a button, it should update the text displayed in the `Text` view, but it doesn't seem to refresh the UI as expected. Here’s a minimal example of my code: ```swift import SwiftUI class MyModel: ObservableObject { @Published var text: String = "Initial Text" } struct ContentView: View { @StateObject private var model = MyModel() var body: some View { NavigationView { VStack { Text(model.text) .padding() Button("Update Text") { model.text = "Updated Text" } } .navigationTitle("State Update Test") } } } @main struct MyApp: App { var body: some Scene { WindowGroup { ContentView() } } } ``` I've tried a couple of things to troubleshoot this scenario. First, I ensured that the `@StateObject` is initialized in the `ContentView`. I also attempted to replace `@StateObject` with `@ObservedObject`, but that didn't change the behavior either. No errors are thrown during execution, but the UI simply doesn't reflect the state change when I press the button. I also checked for issues related to the `NavigationView`, but nothing seemed to work. To further investigate, I added print statements inside the button action and the `MyModel` class to confirm if the state is being changed. The print statements confirm that the button tap is indeed updating the `text` property, but the UI remains exploring on the initial value. Could this be an scenario with how `NavigationView` handles state updates, or am I missing something in the setup that prevents the view from refreshing in iOS 17? Any insights or suggestions would be greatly appreciated!
