WatchKit
From Wikipedia, the free encyclopedia
WatchKit is a framework provided by Apple to develop applications for the Apple Watch. The WatchKit framework is designed for the Swift programming language and also the Objective-C programming language and must be compiled in Xcode, similar to iOS applications.[1]
WatchKit was first released in 2014, one year before the release of the Apple Watch.[2] It was bundled in with the iOS 8.2 beta SDK.[3] In 2015, Apple set up WatchKit labs in several different cities to allow for in-person development of Apple Watch applications before the product's official launch.[4]
Functionality
WatchKit provides classes allows for development of applications on the Apple Watch. WatchKit also enables iOS applications to send notifications and "Glances," which are persistent notifications that are created using predefined templates made by Apple.[5] The framework is designed to be used with either Swift or Objective-C, and must be compiled in Xcode. While it is designed for the Apple Watch, the watch itself only renders the user interface, and an iPhone linked with the watch renders everything else. It also allows for Handoff support with the linked iPhone.[6]
