override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view
        let tap = UITapGestureRecognizer(target: self, action: #selector(doubleTapped))
        tap.numberOfTapsRequired = 2
        view.addGestureRecognizer(tap)
    
    }
    
    @objc func doubleTapped(sender: UITapGestureRecognizer) {
        let indexPath = self.collectionView.indexPathForItem(at: sender.location(in: sender.view))

        if let unwrapped = indexPath {

For some reason, indexPath is always nil here. Does anyone see the bug in my code?

You need to get the tap position in your collection view, not the super view.

Use let indexPath = self.collectionView.indexPathForItem(at: sender.location(in: self.collectionView))
