Creating watch interfaces

A watch's user interface is built up of elements in a similar way to iOS applications, except that the user toolkit is built using WatchKit instead of UIKit. In the same way that classes, such as UITableView, exist, corresponding classes, such as WKInterfaceTable, also exist. There are minor differences; for example, the UITableView will dynamically populate the elements upon display, but the WKInterfaceTable will expect to be told in advance how many rows exist and what these rows are.

Adding a list of users to the watch

Unlike the UITableView, which provides section headers to group rows, a WKInterfaceTable only permits a single list of items. Instead, the application will be designed so that the first screen will show a list of users, and then the second screen will show the selected user's repositories.

For testing purposes, add the following into the applicationDidFinishLaunching method of the ExtensionDelegate class:

api = GitHubAPI.connect()
