Swift UICollectionView Cell Transition Effect

Question

I use full frame UICollectionView as PageViewController. I want to add transition style when passing next/previous item. Normally cells are following each other start points and end points but I want to give an effect that "CrossFade" effect like in this library - https://github.com/KelvinJin/AnimatedCollectionViewLayout .

But I want to keep the first cell in the backgorund and second cell cover the first cell "like lay a sheet" .

Thanks in advance
