Answer 1

If someone uses sender : UITapGestureRecognizer this might be helpful.

@objc func popupSettings(sender : UITapGestureRecognizer) {
    .....
    if let popoverPresentationController = alert.popoverPresentationController {
        popoverPresentationController.sourceView = self.view
        popoverPresentationController.sourceRect = CGRect(origin: sender.location(in: self.view), size: CGSize(width: 1.0, height: 1.0))
    }
    self.present(alert, animated: true, completion: nil)
}

Answer 2

var actionSheet = UIAlertController(title: "Please Select Camera or Photo Library", message: "", preferredStyle: .actionSheet)

if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad ){
    actionSheet = UIAlertController(title: "Please Select Camera or Photo Library", message: "", preferredStyle: .alert)
}

actionSheet.addAction(UIAlertAction(title: "Upload a Photo", style: .default, handler: { (UIAlertAction) in
    self.openPhotoLibrary()
}))
actionSheet.addAction(UIAlertAction(title: "Take a Photo", style: .default, handler: { (UIAlertAction) in
    self.openCamera()
}))
actionSheet.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
self.present(actionSheet, animated: true, completion: nil)
