Add tap gesture to UIStackView : <p>Im attempting to add a <code>UITapGesture</code> to a <code>UIStackView</code> within a collectionView cell but each time I do my app crashes. (All <code>IBOutlets</code> are connected) This there something I'm doing wrong here?</p>

<pre><code> let fGuesture = UITapGestureRecognizer(target: self, action: #selector(self.showF(_:)))
 cell.fstackView.addGestureRecognizer(fGuesture)

 func showF(sender: AnyObject){
        print(111)
    }
</code></pre>
