title: Can I hide page indicator in UIPageViewController?
body: <p>I make a fullscreen photo's slideshow by using UIPageViewController. Then, I would like to hide page indicator when user tap on picture.</p>
  
  <p>I have tried to used this code but it doesn't immediately hide the indicator on tap.</p>
  
  <pre><code>let appearance = UIPageControl.appearance()
  appearance.isHidden = true
  </code></pre>
