Apple Watchkit simulator issue: SPErrorInvalidBundleNoGizmoBinaryMessage

ios xcode6 watchkit

When I open my existing Watchkit app (Xcode 6.2), it compiles correctly, the simulators are launched (iPhone+Watch), followed by the meaningful error:

Error Launching 'xxx Watchkit Extension' SPErrorInValidBundleNoGizmoBinaryMessage

I have this issue with all simulators (iPhone 5/5S/6/6+ - 38mm/42mm)

Any ideas what the issue can be?

It seems for some reason the application does not want to run on the simulator, even though it used to. The iPhone application included in the same project does run, as do other Watchkit sample applications.

Did you change the bundle ID of your app? If so you may need to manually update the WKAppBundleIdentifier in the WatchKit Extension and also the WKCompanionAppBundleIdentifier in the WatchKit App.
