Context

I'm building Unit Tests for the Apple Watch using the XCUITest library. I'd like to take screenshots of the Watch Faces on the simulator, so I was thinking on using the bundle ID of the 'Clock App' via the:

XCUIApplication(bundleIdentifier: "com.bundle.applicationName")

But I can't seem to be able to control the watch faces on my UI Test.

Specific Question

• Is there a way to get Apple's Watch Application's Bundle IDs?
• Alternatively, is there a better way of trying to control the Watch Faces?
