CollectionViewCell add shadow

I want to add a shadow to my CollectionViewCell, but the following code doesn't work.

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! myCell
        
        // Configure the cell
        cell.layer.cornerRadius = 15.0
        cell.layer.masksToBounds = true
        cell.layer.borderWidth = 0.0
        
        cell.backgroundView?.layer.shadowColor = UIColor.black.cgColor
        cell.backgroundView?.layer.shadowRadius = 5
        cell.backgroundView?.layer.shadowOpacity = 1
        cell.backgroundView?.layer.shadowOffset = CGSize(width: 0, height: 0)
        
        
        return cell
    }

I also tried:

cell.layer.shadowColor = UIColor.green.cgColor
cell.layer.shadowRadius = 5
cell.layer.shadowOpacity = 1
cell.layer.shadowOffset = CGSize(width: 0, height: 0)


I don't get an error, but no shadow occurs.

As far as I tried, with adding shadow settings directly to the `layer` of the cell, I could see the shadow:

    override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! MyCell
        
        // Configure the cell
        cell.layer.cornerRadius = 15.0
        cell.layer.borderWidth = 0.0
        cell.layer.shadowColor = UIColor.black.cgColor
        cell.layer.shadowOffset = CGSize(width: 0, height: 0)
        cell.layer.shadowRadius = 5.0
        cell.layer.shadowOpacity = 1
        cell.layer.masksToBounds = false //<-
        
        return cell
    }

Please do not forget to set false to `cell.layer.masksToBounds`.
