## Discussion

Discussion The following example uses the thick material as the sheet background: struct ContentView: View {     @State private var showSettings = false

var body: some View {         Button("View Settings") {             showSettings = true         }         .sheet(isPresented: $showSettings) {             SettingsView()                 .presentationBackground(.thickMaterial)         }     } } The presentationBackground(_:) modifier differs from the background(_:ignoresSafeAreaEdges:) modifier in several key ways. A presentation background: Automatically fills the entire presentation. Allows views behind the presentation to show through translucent styles on supported platforms. note: Sheet presentations on macOS do not support translucency or transparency — the background is always opaque.
