Picker Label not showing anymore
The Label for Picker is not being displayed anymore is there a way to fix this? The label used to show in earlier versions instead of the first option. struct ExampleView: View { var fruits = ["Banana","Apple", "Peach", "Watermelon", "Grapes" ] @State private var selectedFruit = 0 var body: some View { VStack { Picker(selection: $selectedFruit, label: Text("Select Favorite Fruit")) { ForEach(0..<fruits.count) { Text(self.fruits[$0]) } } Text("Your Favorite Fruit: \(self.fruits[selectedFruit])") } .pickerStyle(MenuPickerStyle()) } }

Navigation Stack Management
struct Testing: View {     @EnvironmentObject var navHelp : NavigationHelper     var body: some View {         NavigationView {             VStack { NavigationLink(destination:testing2(), tag : "testing2", selection : $navHelp.selection) { Text("Go to two") }             }             .navigationBarTitle("Navigation")         }     } } struct testing2 : View {     @EnvironmentObject var navHelp : NavigationHelper          var body: some View{         VStack {             NavigationLink(destination:testing3(), tag : "testing3", selection : $navHelp.selection) { Text("Go to 2n3") }         }         .navigationBarTitle("Second Page")     } } struct testing3 : View {     @EnvironmentObject var navHelp: NavigationHelper     var body: some View{         VStack {             Button(action: {                     navHelp.selection = "testing2"             }, label: {                 Text("Go to two")             })         }         .navigationBarTitle("Third Page")     } } class NavigationHelper: ObservableObject {     @Published var selection: String? = nil } I am trying to navigate to any page inside of my NavigationView. I made an ObservableObject and passed it in as an EnvironmentObject. I found a similar answer on stack about this. I can get it to work to returning to the first page by setting the value to nil or the second page by setting the selection to testing2. How do I get it to work with another layer? When I add a new tagged NavigationLink the NavigationView automatically goes back to the top of the stack.
