Develop Apple Watch Apps – WatchKit SDK Released!

The wait is over, with the beta release of Xcode 6.2 and iOS 8.2 SDK, you can now begin development of applications for Apple Watch!

An application for Apple Watch consists of a WatchKit extension that runs on the iPhone as well as user interface resources that are installed on the Apple Watch.

“When your app is launched on Apple Watch, the WatchKit extension on iPhone runs in the background to update the user interface and respond to user interactions. WatchKit provides three opportunities to extend your iPhone app to Apple Watch: WatchKit apps, Glances, and actionable notifications.”
