title: CollectionView inside ScrollView
body: <p>So my problem is that every time that I'm trying to scroll, scroll view doesn't work. Only the scroll of the collection view is working.</p>
  
  <p>I have my <code>ViewController</code> and this subviews:</p>
  
  <pre><code>. View
  .. Scrollview
  ... Label
  ... Image 
  ... Label
  ... CollectionView (column of 2)
  </code></pre>
  
  <p>I tried to disable scroll in collection view but nothing is working as expected.</p>
