CollectionView sizeForItemAtIndexPath never called

Question

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

class PhrasesCompactCollectionViewController: UICollectionViewController
         


        

Answer 1

Three things you need to check if no answer works:

1. Implement FlowLayout Delegate : class MyController: UICollectionViewController, UICollectionViewDelegateFlowLayout

2. Use method for size of item for swift 3.0+: func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { return CGSize(width: (collectionView.frame.width / 3) - 1, height: collectionView.frame.width) }

3. Select Estimate size = None in Inspect element of UICollectionView.
