When the UICollectionView is populated with items they always go right to the edges of the UICollectionView like so:
--------------- |X X X X X X X| |X X X X
Swift 2.0
self.automaticallyAdjustsScrollViewInsets = false self.collectionView.contentInset = UIEdgeInsets(top: 10, left: 0, bottom: 0, right: 0)
