Every application we’ve built so far has been constructed from views and controls provided as part of the UIKit framework. You can do a lot with the UIKit stock components, and a great many application interfaces can be constructed using only these objects. Some applications, however, can’t be fully realized without looking further. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
