# dialogSuppressionToggle(isSuppressed:) Enables user suppression of dialogs and alerts presented within `self`, with a default suppression message on macOS. Unused on other platforms. ``` nonisolated func dialogSuppressionToggle(isSuppressed: Binding) -> some View ``` ## Parameters `isSuppressed` Whether the suppression toggle is on or off in the dialog. ## Discussion Applying dialog suppression adds a toggle to dialogs on macOS, which allows the user to request the alert not be displayed again. Typically whether a dialog is suppressed is stored in `AppStorage` and used to decide whether to present the dialog in the future. The following example configures a `confirmationDialog` with a suppression toggle. The toggle’s state is stored in `AppStorage` and used to determine whether or not to show the dialog when the “Delete Items” button is pressed. ``` struct ConfirmEraseItems: View { @State private var isShowingDialog = false @AppStorage("suppressEraseItemAlert") private var suppressAlert = false var body: some View { Button("Delete Items") { if !suppressAlert { isShowingDialog = true } else { // Handle item deletion. } } .confirmationDialog( "Are you sure you want to erase these items?", isPresented: $isShowingDialog ) { Button("Erase", role: .destructive) { // Handle item deletion. } Button("Cancel", role: .cancel) { isShowingDialog = false } } .dialogSuppressionToggle(isSuppressed: $suppressAlert) } } ``` --- Copyright © 2026 Apple Inc.
