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

Try removing all of your UIGestures from the view then test to see if the UICollectionView Cells are able to be interacted with normally.

In my case, I had to remove the lines:

let tap = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard))
    self.view.addGestureRecognizer(tap)
