CollectionView sizeForItemAtIndexPath never called

Question

This is driving me crazy! I have a UICollectionViewController as shown below:

class PhrasesCompactCollectionViewController: UICollectionViewController
         


        

Answer 1

Just add: UICollectionViewDelegateFlowLayout

class YourClass: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {}
