UICollectionView how to deselect all

Question

I have a FollowVC and FollowCell Setup with collection View. I can display all the datas correctly into my uIcollection view cell using the following code with no problem.

Answer 1

To simplify further, you could just do

followCollectionView.allowsSelection = false
followCollectionView.allowsSelection = true

This will in fact correctly clear your followCollectionView.indexPathsForSelectedItems even though it feels very wrong.
