Use this method when you need to show an alert to the user. The example below displays an alert that is shown when the user toggles a Boolean value that controls the presentation of the alert:
struct OrderCompleteAlert: View {
private var isPresented = false
var body: some View {
Button("Show Alert", action: {
isPresented = true
})
.alert(isPresented: $isPresented) {
Alert(title: Text("Order Complete"),
message: Text("Thank you for shopping with us."),
dismissButton: .default(Text("OK")))
}
}
}
