Create UIAlertController with OK Button in Swift

In this short Swift code example we will create an Alert dialog message with only one “OK” button.

  • Create UIAlertController with Title and Message to display
  • Add UIAlertAction or OK button to UIAlertController
  • Handle UIAlertAction to know when user taps on OK button
let alertController = UIAlertController(title: "Alert title", message: "Message to display", preferredStyle: .alert)
        let OKAction = UIAlertAction(title: "OK", style: .default) { (action:UIAlertAction!) in
            // Code in this block will trigger when OK button tapped.
            print("Ok button tapped");
        self.present(alertController, animated: true, completion:nil)
