SwiftUI Navigation Bar Title doesn't appear - swiftui

Question

I'm not sure if anything changed in Beta 3, however, when trying to add the NavigationBarTitle modifier to NavigationView, it does not show the text for the title? Any ideas?
NavigationView {
List(0 ..< 20) { item in
NavigationLink(destination: Text("1")) {
Text("Navigate 1")
}
}
}.navigationBarTitle(Text("Update")).navigationBarHidden(false)
}
The list shows but no title for the list in the NavigationView

Answer 1

You're setting .navigationBarTitle and .navigationBarHidden on NavigationView when they should be modifiers on List instead:
NavigationView {
List(0..<20) { item in
NavigationLink(destination: Text("1")) {
Text("Navigate 1")
}
}
.navigationBarTitle("Update")
.navigationBarHidden(false)
}
You can also just remove .navigationBarHidden(false) (unless you're setting it to true in a previous view or something).

Answer 2

Your code works fine and the navigationBarTitle is not outdated. It must be placed above (inside the Navigation View). Yes, it is sometimes confusing, it is necessary to remember this.
To the place where you currently have it .navigationBarTitle(Text ("Update")).navigationBarHidden(false) you need to set the modifier .navigationViewStyle(StackNavigationViewStyle ()), which means that you should always show the first screen regardless of the screen size.
var body: some View {
NavigationView {
List(0 ..< 20) { item in
NavigationLink(destination: Text("1")) {
Text("Navigate 1")
}
}
.navigationBarTitle(Text("Update"), displayMode: .automatic).navigationBarHidden(false)
}
// that means only show one view at a time no matter what device I'm working
.navigationViewStyle(StackNavigationViewStyle())
}
