UICollectionView only calling didSelectItemAtIndexPath if user double taps, will not call when user single taps

Question

I have a UICollectionView which is about the size of the screen. The UICollectionViewCells that it displays are the same size as the collectionView. Each cell has a UIImage

Answer 1

If you use only didselect:

self.collectionView.allowsMultipleSelection = false

Or delete that line.
