this is a pretty straightforward question, but I haven\'t been able to find a definitive answer to it on SO (if I missed it, please correct me).
Basically, my quest
For iOS 9+
Reverse your collectionView in viewDidLoad() with this :
myCollectionView.transform = CGAffineTransform(scaleX: -1, y: 1)
Reverse-Back your cell (because all things is mirrored) in cellForItemAt with this :
cell.transform = CGAffineTransform(scaleX: -1, y: 1)
Now content is on right side and scroll starts from right.
