In this short Swift code example we will turn UIAlertController into an ActionSheet with three buttons.

• Create UIAlertController of preferredStyle Action
• Create OK button of Default style
• Create Cancel button of Cancel style
• Create Delete button with “Destructive” style
• Handle an Action for each button
• Present Action Sheet to user

  
import UIKit

class ViewController: UIViewController  {

override func viewDidLoad() {
    super.viewDidLoad()
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    
    
    let alertController = UIAlertController(title: "Action Sheet", message: "What would you like to do?", preferredStyle: .actionSheet)
    
    let sendButton = UIAlertAction(title: "Send now", style: .default, handler: { (action) -> Void in
        print("Ok button tapped")
    })
    
    let  deleteButton = UIAlertAction(title: "Delete forever", style: .destructive, handler: { (action) -> Void in
        print("Delete button tapped")
    })
    
    let cancelButton = UIAlertAction(title: "Cancel", style: .cancel, handler: { (action) -> Void in
        print("Cancel button tapped")
    })
    
    
    alertController.addAction(sendButton)
    alertController.addAction(deleteButton)
    alertController.addAction(cancelButton)
    
    self.navigationController!.present(alertController, animated: true, completion: nil)
    
}
}
