Answer 1

func showAlertAction(title: String, message: String){
    let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertController.Style.alert)
    alert.addAction(UIAlertAction(title: "Ok", style: UIAlertAction.Style.default, handler: {(action:UIAlertAction!) in
        print("Action")
    }))
    alert.addAction(UIAlertAction(title: "Cancel", style: UIAlertAction.Style.default, handler: nil))
    self.present(alert, animated: true, completion: nil)
}
