Xcode 6 under yosemite crash

Question

When i try to run any project on any DEVICE (not simulator) on any iOS in Xcode 6 (any version including 6.0.1 and all betas) under yosemite Xcode crashes right after "Build succeeded". the log shows:

Application Specific Information:

ProductBuildVersion: 6A317

I tried to delete the com.apple.dt.Xcode.plist & reinstall Xcode but it keeps crashing on devices, On simulator it works.

Help please.

Answer 1

The solution for me was to remove Urdu language from the list (System preferences>Language and Region). It was set as primary. I kept only English and after restarting Xcode is not crashing anymore.
