WatchKit is a framework from Apple that allows developers to build apps and extensions for the Apple Watch from their existing iPhone apps. There are opportunities to extend iPhone app features to the Apple Watch through glances and notifications. Apple Watch comes in 38mm and 42mm sizes with resolutions of 272-by-340 and 312-by-390 pixels respectively. Developers need Xcode 6.2 or higher with iOS 8.2 and knowledge of Objective-C or Swift to start building Apple Watch apps. Data can be transferred between the iPhone and Apple Watch apps using app groups and user defaults with the app group suite name.

watch app
We can achieve this by using “App Groups” which you need to enable under
capabilities. You also need to create an “App Group” in the developer portal
