How to present multiple sheets

Updated for Xcode 15

If you want to show multiple sheets in SwiftUI, it’s only possible by triggering the second sheet from inside the first – you shouldn’t attach both sheet() modifiers to the same parent view.

Instead, place one sheet() modifier inside the view being used as your first sheet, like this:

struct ContentView: View {
    @State private var showingFirst = false
    @State private var showingSecond = false

    var body: some View {
        VStack {
            Button("Show First Sheet") {
                showingFirst = true
            }
        }
        .sheet(isPresented: $showingFirst) {
            Button("Show Second Sheet") {
                showingSecond = true
            }
            .sheet(isPresented: $showingSecond) {
                Text("Second Sheet")
            }
        }
    }
}

Using this approach, both sheets will be displayed correctly.

If you do place both sheet() modifiers in the same parent, SwiftUI will display a warning: “Currently, only presenting a single sheet is supported. The next sheet will be presented when the currently presented sheet gets dismissed.” That might be exactly what you want, but the warning suggests that this behavior might change in the future.
