The DataSource is a non-UI component that processes the data operations for the UI for iOS data controls, as well as UITableView and UICollectionView. It feeds the consumed raw data into a grouped, sorted or filtered view. This view is then consumed by data controls, such as the ListView.
DataSource can consume various data - from arrays with simple items and business objects, to a dictionaries coming from various sources, such as web services that return data in JSON format.
