What is the technique to expand a SwiftUI MapKit's Map beyond the NavigationBar and TabBar?

edit

To expand a SwiftUI MapKit's Map beyond the NavigationBar and TabBar, you can embed the map in a ZStack and set the edgesIgnoringSafeArea to .all:

struct ContentView: View {
    var body: some View {
        ZStack {
            MapView()
            .edgesIgnoringSafeArea(.all)

            VStack {
                Text("Map Title")
                    .font(.largeTitle)
                    .foregroundColor(.white)
                    .padding()

                Spacer()
            }
        }
    }
}

struct MapView: UIViewRepresentable {
    func makeUIView(context: Context) -> MKMapView {
        MKMapView(frame: .zero)
    }

    func updateUIView(_ uiView: MKMapView, context: Context) {
    }
}

This will allow the map to extend beyond the safe area and fill the entire screen.
