I want to set the background color for the entire app using SwiftUI.

What is the idiomatic way to do this?

I know there is an option to set a background color using a ZStack approach:

import SwiftUI

struct ContentView: View {
  var body: some View {
    ZStack { // 1
      Color.powder950.ignoresSafeArea() // 2
      
      Text("Hello, world!")
    }
  }
}

#Preview {
  ContentView()
}

But it seems repetitive to set a ZStack with a background color on each newly created screen.

Is there a way to set a background color for the entire app globally?
