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

I was just having the same problem and it turned out that there was a UITapGestureRecognizer on the UIView containing the UICollectionView and it was responding instead.

That explains why didSelectItemAtIndexPath works only if the user taps with two fingers or long presses with one finger because that doesn't trigger the UITapGestureRecognizer.

So, check all the UITapGestureRecognizer you got there, not necessarily on the UICollectionView directly but it could be on any UIView containing it.
