Swift alert view with OK and Cancel: which button tapped?

Question

I have an alert view in Xcode written in Swift and I\'d like to determine which button the user selected (it is a confirmation dialog) to do nothing or to execute something.

You can easily do this by using UIAlertController

let alertController = UIAlertController(
       title: "Your title", message: "Your message", preferredStyle: .alert)
let defaultAction = UIAlertAction(
       title: "Close Alert", style: .default, handler: nil)
//you can add custom actions as well 
alertController.addAction(defaultAction)

present(alertController, animated: true, completion: nil)

.
