At your Datasource method

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
      if let subOptioncell : SubOptionsCollectionViewCell = collectionView.dequeueReusableCell(withReuseIdentifier: subOptionsCVReuseIdentifier, for: indexPath) as! SubOptionsCollectionViewCell{
         //... your code
         subOptioncell.addGestureRecognizer(tap)
         return subOptioncell
       }

}

Then at the function cellTapped()

func cellTapped(sender: UITapGestureRecognizer){

    let tapLocation = sender.location(in: yourCollectionView)
    let indexPath : IndexPath = yourCollectionView.indexPathForItem(at: tapLocation)!

    var currentIndex = 0

    if let cell = yourCollectionView.cellForItem(at: indexPath){
        currentIndex = cell.tag
    }

    print("Your Selected Index : \(currentIndex)")
}

Happy Coding!!!
