How to programmatically dismiss UIAlertController without any buttons?

Question

I\'m presenting an UIAlertViewController without any buttons, as it is supposed to just inform users that uploading is in progress. The app is supposed to upload some files

Nothing above seemed to work, but here is what works for me perfectly (xcode 10, swift 5). Enjoy!

Step 1: Place this is your viewController Class

    var newQuestionAlert:UIAlertController?

Step 2: Create function to show alert

  func ShowNewQuestionPopup() {
    if newQuestionAlert == nil {
        newQuestionAlert = UIAlertController(title: "Notice", message: "Next Question Starting", preferredStyle: .alert)
        if let newQuestionAlert = newQuestionAlert {
            newQuestionAlert.addAction(UIAlertAction(title: "OK", style: .default, handler: { action in
                self.newQuestionAlert = nil
                return
            }))
            self.present(newQuestionAlert, animated: true, completion: nil)
         }
     }
 }

Step 3: Create function to dismiss alert

func autoDismiss() {
    newQuestionAlert?.dismiss(animated: false, completion: nil)
    newQuestionAlert = nil
}

Step 4: Call functions as needed
