When I run the app in Xcode IOS 6 beta 2 firmware on the device 8 Beta 2, I get the error message: "dyld: could not load inserted library '/ USR / Library / libgmalloc.dylib", because the image was not found. "
What could be the problem?
This is because Xcode mount wrong DeveloperImage. If you open the Settings-> Developer you will see that the "Enable UIAutomation» and others are missing.
For fix:
This is the only thing that helped me. Even re-flashing on ios8 beta2 does not helps.
