How can I add navigation to an existing program. I coded this as per youtube video: var body: some View { NavigationView { VStack { NavigationLink(destination: viewdetail()) { Text("click") .frame(width: 300, height: 150, alignment: .center) .background(Color.gray) .foregroundColor(.black) } } } It doesn't work. If I comment out the rest of the program it works. I have VStacks and HStacks and functions after the navigation code. Please help.
