swift - How change background color if using NavigationView in SwiftUI?

Question

I want to change background color for full screen. I am using NavigationView, and I want to set Gray color for background (not default white)

struct ContentView : View {
    var body: some View {
        NavigationView {
            ScrollView {
                Text("Example")
            }
            .navigationBarTitle("titl")
        }
    }
}

Setting .background(Color.red) does not work in any place.

If you just embed your content in the NavigationView within a ZStack you should be able to throw the color in underneath your main content.

struct ContentView : View {
    var body: some View {
        NavigationView {
            ZStack {
                Color.red.edgesIgnoringSafeArea(.all)
                ScrollView {
                    Text("Example")
                }
                .navigationBarTitle("title")
            }
        }
    }
}
