You need to trigger delegate functions from custom UICollectionViewCell

Here is my working sample code for Swift3

CollectionViewController

override func viewDidLoad() {
    super.viewDidLoad()
    let editMenuItem = UIMenuItem(title: "Edit", action: NSSelectorFromString("editCollection"))
    let deleteMenuItem = UIMenuItem(title: "Delete", action: NSSelectorFromString("deleteCollection"))
    UIMenuController.shared.menuItems = [editMenuItem, deleteMenuItem]

}

override func collectionView(_ collectionView: UICollectionView, shouldShowMenuForItemAt indexPath: IndexPath) -> Bool {
    return true
}

override func collectionView(_ collectionView: UICollectionView, canPerformAction action: Selector, forItemAt indexPath: IndexPath, withSender sender: Any?) -> Bool {
    return action == NSSelectorFromString("editCollection") || action == NSSelectorFromString("deleteCollection")
}

override func collectionView(_ collectionView: UICollectionView, performAction action: Selector, forItemAt indexPath: IndexPath, withSender sender: Any?) {
    print("action:\(action.description)")
    //Custom actions here..
}

Add following functions to your custom UICollectionViewCell

override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
    return action == NSSelectorFromString("editCollection") || action == NSSelectorFromString("deleteCollection")
}

To call delegate function from cell (needs to be in your custom UICollectionViewCell)

func editCollection()
{
    let collectionView = self.superview as! UICollectionView
    let d:UICollectionViewDelegate = collectionView.delegate!
    d.collectionView!(collectionView, performAction: NSSelectorFromString("editCollection"), forItemAt: collectionView.indexPath(for: self)!, withSender: self)
}
func deleteCollection()
{
    let collectionView = self.superview as! UICollectionView
    let d:UICollectionViewDelegate = collectionView.delegate!
    d.collectionView!(collectionView, performAction: NSSelectorFromString("deleteCollection"), forItemAt: collectionView.indexPath(for: self)!, withSender: self)
}
