  1. And in the updateUI() the questionCounter.text and the progressView should only working if questionNumber <= allQuestions.list.count – 1{
    questionCounter.text = "(questionNumber + 1)/(allQuestions.list.count)"
    progressView.frame.size.width = (view.frame.size.width / CGFloat(allQuestions.list.count)) * CGFloat(questionNumber + 1)
    }

  2. Everything works fine for me. Mij Alf's problem is perhaps the drag and drop trap 🙂 In the Video-Tutorial you place the updateUI() in the updateQuestion() after the if/else block. In the source code in github the updateUI() call is in the if block. That's all. Thank you so much for this awesome and short tutorial.
