Learn WatchKit for iOS covers the development of applications for the new Apple Watch using the
WatchKit framework in iOS 8 and the Swift programming language. In this book an Apple Watch
application is an extension to an existing iOS app and is packaged and submitted to the App
Store along with it. Using a suite of simple examples Kim Topley co-author of Beginning
iPhone Development with Swift introduces and explains every feature of WatchKit and the
associated technologies that you'll need to understand to build Apple Watch applications for
iOS 8 culminating in a complete WatchKit application that shows weather forecast information
for various cities around the world on the Apple Watch.
