→Summary
The WKInterfacePicker class provides a way for developers to design WatchKit app behavior which responds to input from the Digital Crown control located on the side of the Apple Watch device. The picker object allows content to be presented in a number of different styles and navigated and selected using the Digital Crown. Content can be presented in list form including text and images or as a series of stacked images. Alternatively, content may also be presented in the form of an animation sequence.
Having covered the basics of the WKInterfacePicker class, the next two chapters ([[A watchOS 2 WatchKit Picker Tutorial ]] and [[A WatchKit WKInterfacePicker Coordinated Animation Example]]) will work through examples of practical implementations of the picker object.
