Apple released watchOS to the public with the release of the Apple Watch in April 2015. However, with the release of watchOS 2 in September 2015, developers have been able to write extensions that run on the watch itself rather than relying on a companion iOS device being available. This chapter will show how to add watch support to the existing Repository Browser application (created in Chapter 7, Building a Repository Browser.)
This chapter will present the following topics:
Adding a watch extension to an existing project
The type of watch interfaces
Using tables, text, and images
How to transition between screens with selected context
Best practices for watch applications
