Connect your code to storyboard elements using interface controllers, interface objects, and event handlers.
The WatchKit framework includes classes to control user interface elements that you lay out in your storyboard. Storyboard-based layouts typically require an interface controller for each scene. Each controller can manage a number of controls and subviews, such as tables, buttons, sliders, and other visual elements. Use the classes in this collection to configure your visual elements at runtime, and to respond to user interactions.
