Instead of trying to force didSelectItem you can just get the indexPath and/or cell this way:

func tap(sender: UITapGestureRecognizer){

    if let indexPath = self.collectionView?.indexPathForItem(at: sender.location(in: self.collectionView)) {
        let cell = self.collectionView?.cellForItem(at: indexPath)
        print("you can do something with the cell or index path here")
    } else {
        print("collection view was tapped")
    }
}

Whenever you want to add a gesture recognizer, but not steal the touches from the target view, you should set UIGestureRecognizer.cancelsTouchesInView for your gestureRecognizer instance to false.
