UICollectionView is an UIKit view that manages collection of ordered items and presents the items using customizable layout. It was introduced by Apple in WWDC 2012 with the release of iOS 6 SDK. UICollectionView interface is quite similar with the old UITableView as it provides DataSource as a source to display the data and Delegate to handle interaction for each item.
Unlike UITableView that display each row using a fixed list layout inside UITableViewCell, UICollectionView provides flexibility and customizability for developers to provide their own layout by subclassing UICollectionViewLayout, it also supports custom decoration view, customizable size for each individual section view and cells. Apple itself provides us one layout out of the box to use called UICollectionViewFlowLayout.
