SwiftUI: NavigationButton initializer gives error

Inside one of my SwiftUI Views, I have this code: 

NavigationButton(destination: DetailView()) {
    Text(verbatim: "Start")
}

Xcode isn't able to build the code and gives this error: 

'(DetailView, @escaping () -> Text) -> NavigationButton<Text, DetailView>' is not convertible to '(DetailView, Bool, @escaping () -> Bool, () -> Text) -> NavigationButton<Text, DetailView>'

I believe Xcode thinks that I am using the init(destination: Destination, isDetail: Bool, onTrigger: () -> Bool, label: () -> Label) initializer, but I am using the init(destination: Destination, label: () -> Label) one.

The strange thing is that the one I am using is not documented (https://developer.apple.com/documentation/swiftui/navigationbutton) but it is used in multiple tutorials I have seen, for example https://www.hackingwithswift.com/quick-start/swiftui/how-to-push-a-new-view-using-navigationbutton.

So my question is: Is the initializer that I am using wrong or is there a way to avoid the error?

Update: Problem solved, see comments!

Also, earlier release (and some Videos) of "Xcode 11 Beta" show use of "NavigationButton" but it is no longer supported, has been replaced with "NavigationLink".

Try below code:-

struct ContentView: View {
    var body: some View {
        NavigationView {
            NavigationButton(destination: DetailView()) {
                Text("Click")
                }.navigationBarTitle(Text("Navigation"))
        }
    }
}
struct DetailView: View {
    var body: some View {
        Text("Detail")
    }
}
struct ContentView_Previews : PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
