Apple has announced the official availability of its WatchKit SDK for iOS developers. WatchKit provides developers with the tools to design apps for the new Apple Watch, and is being released today so that developers can begin preparing for the new wearable device when it ships next year. The new software development tools will allow third-party developers to build apps for the watch which will let users respond or take action from the watch, or get quick looks at other information — which Apple calls Glances. WatchKit is bundled with the iOS 8.2 beta SDK, available for registered iOS developers to download now as part of the Xcode 6.2 beta. The release is also accompanied by a developer beta of iOS 8.2.
