The UIKit framework provides a wide range of functionality and is used in every single iPhone and iPad application. It encompasses touch and event handling, animations, views, windows, controls, and higher level components such as UITableView and UICollectionView. Your responsibilities will include working closely with the HI design team on new UI concepts and adding features to existing components that complement the future iterations of iPad and iPhone hardware. In addition, you will work cross-functionally with many application developers inside Apple to define the next set of UIKit features and corresponding APIs.
