Use this method to show a popover whose contents are a SwiftUI view that you provide when a bound Boolean variable is true. In the example below, a popover displays whenever the user toggles the isShowingPopover state variable by pressing the “Show Popover” button:

struct PopoverExample: View {
    @State private var isShowingPopover = false


    var body: some View {
        Button("Show Popover") {
            self.isShowingPopover = true
        }
        .popover(isPresented: $isShowingPopover) {
            Text("Popover Content")
                .padding()
        }
    }
}
