goldsdad answer is perfect it also usable for UICollectionViewCell added code below `@objc func buttonClick(_ sender: UIButton) {     var superview = sender.superview       while let view = superview, !(view is UICollectionViewCell) {         superview = view.superview       }       guard let cell = superview as? UICollectionViewCell else {         print("button is not contained in a table view cell")         return       }       guard let indexPath = collectionView.indexPath(for: cell) else {         print("failed to get index path for cell containing button")         return       }       // We've got the index path for the cell that contains the button, now do something with it.       print("button is in row (indexPath.row)")   }`
