PeekDialog

Toast and banner notifications for SwiftUI — same binding-based API as .sheet and .alert. Drop in any view as content, auto-dismiss or swipe away, style it however you want.

On iOS, dialogs live in their own overlay window so they sit above sheets, alerts, and the rest of your UI. Multiple notifications can stack into a queue.

What you get

Familiar API	isPresented: and with: bindings, just like Apple's presentation modifiers
Any content	Text, buttons, images, custom layouts — it's just a SwiftUI view
Auto-dismiss	.short / .medium / .long / .custom(seconds:) / .persistent
Swipe to dismiss	On by default; turn it off with .peekInteractiveDismissDisabled()
Styles	.plain for full control, glass styles on iOS 26+, or roll your own DialogStyle
Stacking (iOS)	peekDialog(items:) queues notifications; top two stay visible
Over everything (iOS)	Window-based presentation above sheets and alerts

Quick start

import SwiftUI
import PeekDialog

struct ContentView: View {
    @State private var showDialog = false

    var body: some View {
        Button("Show") { showDialog = true }
            .peekDialog(isPresented: $showDialog, dismissDelay: .medium) {
                HStack {
                    Image(systemName: "checkmark.circle.fill")
                        .foregroundColor(.green)
                    Text("Saved")
                    Spacer()
                }
                .padding()
            }
    }
}

That's it. Bind state → describe content → PeekDialog handles the rest.

Gotcha: .dialogStyle and .peekInteractiveDismissDisabled must go inside the content closure. Putting them on the view that has .peekDialog does nothing. See Common Mistakes.
