I want to change the background color through a button that the user can press. Does anyone know how I can do that?

You can do something like this:

Code Block Swiftstruct ContentView: View {
	@State private var backgroundColour: Color = .red
	var body: some View {
		ZStack {
			backgroundColour
				.ignoresSafeArea()
			
			Button("Change background colour") {
				backgroundColour = .blue
			}
		}
	}
}

You need to create an @State property to hold the current background colour and update it when the button is tapped.
