swiftui navigationlink state-management Swift

I'm converting an old project and I've been struggling with this for a few days now and could really use some help. I'm experiencing an issue with `NavigationLink` in SwiftUI where the expected state change isn't being reflected after dismissing a modal. I'm using Xcode 14.0 and targeting iOS 16.0. Here's a simplified version of my setup: I have a main view that presents a modal with a `TextField` to update a user's name. When the modal is dismissed, I expect the main view to display the updated name. However, it seems that the state isn't updating correctly, and I still see the old name. Here's the code for my main view: ```swift struct MainView: View { @State private var userName: String = "John Doe" @State private var showingModal: Bool = false var body: some View { NavigationView { VStack { Text("User Name: \(userName)") .padding() NavigationLink(destination: Text("Detail View")) { Text("Go to Detail") } .padding() Button("Edit Name") { showingModal.toggle() } } .sheet(isPresented: $showingModal) { EditNameView(userName: $userName) } } } } ``` And here’s my `EditNameView`: ```swift struct EditNameView: View { @Binding var userName: String var body: some View { VStack { TextField("Enter your name", text: $userName) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding() Button("Done") { // Dismiss the modal } .padding() } } } ``` The `userName` is passed as a binding to the `EditNameView`, but after editing and dismissing the modal, the main view still shows the old name. I've tried adding `@StateObject` and `ObservableObject`, but that didn't resolve the issue. I also verified that the Binding is correctly updating by printing the `userName` in `EditNameView` when the button is pressed. It's showing the updated value. Is there something I'm missing here? Any suggestions would be greatly appreciated! My development environment is Linux. This is part of a larger application I'm building. What am I doing wrong? For reference, this is a production desktop app. Is there a simpler solution I'm overlooking? Thanks in advance!
