Nate Cook is totally right however I would do it so I detect if it is iPad or iPhone.

This is for barButtonItem:

if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad ){

            if let currentPopoverpresentioncontroller = alertController.popoverPresentationController{
                currentPopoverpresentioncontroller.barButtonItem = sender as! UIBarButtonItem
                currentPopoverpresentioncontroller.permittedArrowDirections = UIPopoverArrowDirection.down;
                self.present(alertController, animated: true, completion: nil)
            }
        }else{
            self.present(alertController, animated: true, completion: nil)
        }
