I was building my application and I decided to change the display name. After the change, this error occurred.

Simulating crash: Condition failed:"NO". Couldn't instantiate class _TtC37Capsule_Controller_WatchKit_Extension17HostingController

I changed the display name for the app and the extension. If you could help, that would be appreciated.
