UIActionSheet iOS Swift

Question

How To Do UIActionSheet in iOS Swift? Here is my code for coding UIActionSheet.

@IBAction func downloadSheet(sender: AnyObject)
{
    let optionMenu = UIAlertController(title: nil, message: "Choose Option", preferredStyle: .ActionSheet) 

    let saveAction = UIAlertAction(title: "Save", style: .Default, handler: 
    {
        (alert: UIAlertAction!) -> Void in
        println("Saved")
    })

    let deleteAction = UIAlertAction(title: "Delete", style: .Default, handler:
    {
        (alert: UIAlertAction!) -> Void in
        println("Deleted")
    })

    let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: 
    {
        (alert: UIAlertAction!) -> Void in
        println("Cancelled")
    })
    optionMenu.addAction(deleteAction)
    optionMenu.addAction(saveAction)
    optionMenu.addAction(cancelAction)
    self.presentViewController(optionMenu, animated: true, completion: nil)
}

I hope my Code is clear... I am welcome better suggestion for this code.

The Old Way: UIActionSheet

let actionSheet = UIActionSheet(title: "Takes the appearance of the bottom bar if specified; otherwise, same as UIActionSheetStyleDefault.", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: "Destroy", otherButtonTitles: "OK")
actionSheet.actionSheetStyle = .Default
actionSheet.showInView(self.view)

// MARK: UIActionSheetDelegate

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex  buttonIndex: Int) {
switch buttonIndex {
    ...
   }
}

The New Way: UIAlertController

let alertController = UIAlertController(title: nil, message: "Takes the appearance of the bottom bar if specified; otherwise, same as UIActionSheetStyleDefault.", preferredStyle: .ActionSheet)

let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { (action) in
  // ...
 }
 alertController.addAction(cancelAction)

let OKAction = UIAlertAction(title: "OK", style: .Default) { (action) in
   // ...
}
alertController.addAction(OKAction)

let destroyAction = UIAlertAction(title: "Destroy", style: .Destructive) { (action) in
println(action)
}
alertController.addAction(destroyAction)

self.presentViewController(alertController, animated: true) {
// ...
}
