How to change background color of the NavigationView in SwiftUI?

Question

I'm trying to change background color of the NavigationView (not navigation bar) using this code:

NavigationView {
    Text("Text")
}
.background(Color.clear)

But it doesn't work. Also, I tried to change UIView appearance:

UIView.appearance().backgroundColor = UIColor.black

But it doesn't work too.

The actual result is presented below:

The desired result is:

Does anyone know how to do this?

First look at this result:

As you can see, you can set the color of each element in the View hierarchy like this:

struct ContentView: View {

    init(){
        UINavigationBar.appearance().backgroundColor = .green 
        //For other NavigationBar changes, look here:(https://stackoverflow.com/a/57509555/5623035)
    }

    var body: some View {
        ZStack {
            Color.yellow
            NavigationView {
                ZStack {
                    Color.blue
                    Text("Some text")
                }
            }.background(Color.red)
        }
    }
}

And the first one is window:

window.backgroundColor = .magenta

The issue you faced is we can not remove the background color of SwiftUI's HostingViewController (yet), so you can't see the navigationView (What you called) through the views hierarchy. You should wait for the API or try to fake the navigation view (not recommended).
