CollectionView sizeForItemAtIndexPath never called
<p>This is driving me crazy! I have a UICollectionViewController as shown below: </p>

<pre><code>class PhrasesCompactCollectionViewController: UICollectionViewController
</code></pre>

<p>The numberOfSections and cellForItemAt are being called but the sizeForItemAtIndexPath is never called. I am using the same exact code somewhere else and it fires correctly. I am using Xcode 8 Beta 6.</p>

<pre><code>func collectionView(collectionView: UICollectionView,
                        layout collectionViewLayout: UICollectionViewLayout,
                        sizeForItemAtIndexPath indexPath:  NSIndexPath) -&gt; CGSize {

        return CGSize(width: 120, height:120) 
    }
</code></pre>
