This question already has an answer here: Swift default AlertViewController breaking constraints 1 answer On iOS 12.2. while using UIAlertController's actionSheet Xcode, gives constraint error anyone having this problem This same code runs on iOS 12.1 with no error I have tested this code on Xcode 10.2 and 10.1 class ViewController: UIViewController { let Click : UIButton = { let button = UIButton(type: UIButton.ButtonType.system) button.translatesAutoresizingMaskIntoConstraints = false button.setTitle("OK", for: .normal) button.tintColor = UIColor.blue button.addTarget(self, action: #selector

When writing the handler closure of a UIAlertAction , should the reference to self be strong (the default), weak , or unowned ? There have been posts relevant to this topic ( 1 , 2 , 3 , 4 ) but I honestly don't see how they help in this case.

How to put image on UIActionSheet on right position of text. Like given in apple music player. Note: Don't answer with custom view, if it is possible in UIActionSheet , Kindly let us know. Don't answer with custom view Then you are effectively forbidding anyone to answer, because that is what you do . First of all, there is no such thing as UIActionSheet.

It is also deliberately very simple and limited.

I understand it's not within a ViewController . I am looking for an approach to access it. override func awakeFromNib() { super.awakeFromNib() // Initialization code let tapGestureShareImageView = UITapGestureRecognizer(target: self, action: #selector(self.shareImageTouchUpInside)) shareImageView.addGestureRecognizer(tapGestureShareImageView) shareImageView.isUserInteractionEnabled = true } @objc func shareImageTouchUpInside() { showAction()

I am developing in Swift 2.3 I have an Utils class enabling me to create UIAlertController easily. public class Utils { class func buildAlertInfo(withTitle title: String?, andMessage message: String?, withHandler handler: (UIAlertAction -> Void)?) -> UIAlertController { let alertController = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert) alertController.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: handler)) return alertController } } It enables me to build AlertController with ease : let alert = Utils
