Well-known developers Steve Troughton-Smith, Saurik and Adam Bell have managed to hack the Apple Watch on watchOS 2 to run truly native apps on the device. Although Apple is advertising native apps with watchOS 2, it isn’t as ‘native’ as some developers wanted or expected. The logic code now runs on the watch, but raw access to the user interface is still not allowed on watchOS 2.
This means frameworks like UIKit cannot be used to draw truly custom UI. Instead developers must rely on the same techniques employed with current WatchKit apps that revolve around image sequences to create more interesting effects.
In the demo, video embedded below, the team managed to get a fully interactive 3D object running on the Apple Watch powered by Apple’s SceneKit framework.
