Smooth Drag and Drop of CollectionViewCells between multiple CollectionViews cannot be achived.

I have implemented CollectionView Drag and Drop Delegate into my project to achieve the drag and drop feature on two collection views but my client needed smoother drag and it seems that CollectionView Drag and Drop delegate only supports long press recognizer. How to add PanGestureRecognizer to activate the drag and drop between multiple collection view cells.
