Xcode 7 Beta 4 - Cannot find storyboard every 2nd time I run the project

Question

It might be a beta-prerelease-bug in Xcode, but did anyone other experience the same thing?

I clean the project - Run it - Everything's fine.

Then I stop the project - Run it again - just a black screen and this log:

2015-08-03 23:22:30.743 XXXXXXX[12221:2892479] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'MainStoryboard' in bundle NSBundle </private/var/mobile/Containers/Bundle/Application/920917A0-44DF-4B5F-91A8-BB669DDF5F0D/XXXXXXXX.app> (loaded)'

libc++abi.dylib: terminating with uncaught exception of type NSException

Then I can clean it and do the same thing all over...

And yes, the storyboard is added correctly. It's also added correctly in the info.plist and I have also tried to remove it and add it again. With the same result.

UPDATE I

Same thing happens in the latest Xcode Beta 5.

UPDATE II

This is the log from the second time I ran it in a simulator.

Could it be some kind of Facebook bug in the new SDK?
