Why UICollectionView didSelect method does not work?

Question

I've created my UICollectionView programmatically and in this case my didSelectItemAtIndexPath method does not call at all.

let collectionView = UICollectionView(frame: CGRect(x: 0, y: 0, width: CGRectGetWidth(self.view.frame), height: 360), collectionViewLayout: layout)
collectionView.delegate = self
collectionView.dataSource = self
collectionView.userInteractionEnabled = true

So, what is a problem? Why when I tap on the cells I do not get my response?

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    print("Selected Cell: \(indexPath.row)")
}

Answer 1

I just encountered this case.

Did you put a button or an interactive view in a collection view cell? Your touch is handled by it, then didSelect isn't called.

Turn off User Interaction Enabled property by Interface builder, or set false programmatically.

Answer 2

Be sure that you don't have UICollectionViewDelegate and UICollectionViewDelegateFlowLayout together.

Answer 3

i Know this may be late, but for the sakes of feature purpose, CollectionView[didSelectItem] not responding to touch could be as a result of you also enalbing addGestureRecognizer so check if you have set a gesture recognizer on your CollectionView like so collectionView?.addGestureRecognizer(tapGestRecognizer)

Answer 4

check in UiCollectionviewCell subclass isUserInteractionEnabled property or set it programaticaly to true

self.contentView.isUserInteractionEnabled = true
