Typically, a watch user interface will present information to the user or let them select or manipulate it in some way. When items are presented in a table, then it is natural to let the user tap on the row to show a subsequent screen. Watch applications use segues to move from one screen to another in a similar way to iOS applications.

The first step will involve creating a new controller file called RepositoryListController.swift. This will be used to hold the RepositoryListController and RepositoryRowController classes, in a very similar way to the existing InterfaceController. As with the other view, there will be a table to store the rows, and each row will have a name label:

class RepositoryRowController: NSObject {
  @IBOutlet weak var name: WKInterfaceLabel!
}
class RepositoryListController: WKInterfaceController {
  let delegate = WKExtension.sharedExtension().delegate as! ExtensionDelegate
  @IBOutlet weak var repositoriesTable: WKInterfaceTable!
}
