I am using xcode 7.1.1, along with the latest versions of the simluators, yet I am unable to test localization on the watch. My Watch.app simply displays Complications > and the app that I am testing. There's no place in the simulator to change the Watch region/language, like there is in the Watch.app on the iPhone. Is there an update that I am missing or a setting that I need to change? This is a fairly critical feature to have missing.
To work around this problem, I've had to test my strings one at a time, by replacing the Localizable.strings file for the Base language, with the translated strings files, which is absurd.
