  <p>There is vertical page curl animation:</p>
  
  <pre><code>UIView.transition(with: self.myView, duration: 0.7, 
  options: .transitionCurlDown, animations: {
  })
  </code></pre>
  
  <p>Important: I don't want to use transition between UIViewControllers or UIPageControllers, I want to apply animation on UIView on the current screen.</p>
