The error it is pretty self explanatory. You can use it like this: var animationRect = frame.inset(by: UIEdgeInsets(top: padding, left: padding, bottom: padding, right: padding)) or simply var animationRect = frame.insetBy(dx: padding, dy: padding)
You should call all code from showAlertMessage on main queue: class func showAlertMessage(message:String, viewController: UIViewController) { DispatchQueue.main.async { let alertMessage = UIAlertController(title: “”, message: message, preferredStyle: .alert) let cancelAction = UIAlertAction(title: “Ok”, style: .cancel) alertMessage.addAction(cancelAction) viewController.present(alertMessage, animated: true, completion: nil) } }
I fixed the problem. Select target -> General -> select Devices with Universal and select Main Interface for iPhone & iPad.
