swiftui navigation state-management swift

I'm experimenting with Could someone explain I'm working with an scenario where a `NavigationLink` in SwiftUI is not updating the view state correctly after dismissing a modal view in iOS 17. I have a main view where I use a `NavigationLink` to navigate to a detail view. When I present a modal from the detail view and then dismiss it, the main view should reflect updated data, but it doesn't. Here's a simplified version of my code: ```swift struct MainView: View { @State private var data: String = "Initial Data" var body: some View { NavigationView { VStack { Text(data) NavigationLink(destination: DetailView(data: $data)) { Text("Go to Detail") } } } } } struct DetailView: View { @Binding var data: String @State private var showModal: Bool = false var body: some View { VStack { Text("Detail View") Button("Show Modal") { showModal.toggle() } .sheet(isPresented: $showModal) { ModalView(data: $data) } } } } struct ModalView: View { @Binding var data: String var body: some View { Button("Update Data") { data = "Updated Data" } } } ``` After I tap the "Update Data" button in the `ModalView` and dismiss the modal, the `MainView` does not show the updated data. I've verified that the `data` variable in `DetailView` gets updated correctly, but the `MainView` is still displaying the initial value. I’ve tried using `@ObservedObject` instead of `@Binding`, but that led to issues with the state not being maintained during navigation. I've also confirmed that the modal is being dismissed properly, but I still need to see the results reflected in the `MainView`. Is there something I'm missing with SwiftUI's state management, or is there a better approach to ensure that my views stay in sync after dismissing a modal? Is there a simpler solution I'm overlooking?
