Q: SwiftUI - navigationBarTitle transparent error - swift

Question

UPDATE: Resolved - This topic is just a beta bug.
I'm having a problem with the navigationBarTitle in SwiftUI.
I'm using a NavigationLink to go to a second view with a list. This view has a navigationBarTitle like the first view. But in the second view I can push the list behind the navigationBarTitle.
When I'm going from a third view back to the second the navigationBarTitle works as it should be.
Does anyone else having this problem? I'm using Xcode Version 11.0 GM (11A419c)
Here is the code:
struct ContentView: View {
private var line : [String] = ["Line 1", "Line 2", "Line 3"]
var body: some View {
NavigationView {
List {
ForEach(line, id: \.self) { item in
NavigationLink(destination: DetailView()) {
TestCell(lineName: item)
}
}
}
.navigationBarTitle("Main View")
}
}
}
struct TestCell: View {
let lineName: String
var body: some View {
Text(lineName)
}
}
struct DetailView: View {
var body: some View {
List() {
NavigationLink(destination: DetailDetailView()) {
Text("To the next view")
.foregroundColor(Color.red)
}
}
.navigationBarTitle("Detail View")
}
}
struct DetailDetailView: View {
var body: some View {
Text("Hello World!")
.navigationBarTitle("Detail Detail View")
}
}
