title: UICollectionView in iOS 10 is misaligning cells
body: <p>I have a collection view that used to look like this (iOS 9-):</p>
  
  <p><a href="https://i.stack.imgur.com/CF1V5.png" rel="nofollow"><img src="https://i.stack.imgur.com/CF1V5.png" alt="Correctly (and previously) displayed UICollectionView"></a></p>
  
  <p>As of iOS 10 however, that exact same untouched collection view is displaying like this:</p>

  <p>No constraints or anything really have been changed from iOS 9 to iOS 10. I simply cannot figure out what the issue is. If it helps, the only constraints on this collection view are 0 spacing stuck to top, left, right and bottom:</p>

  <p>Any help is greatly appreciated.</p>
