what should i do now ?

Thanks in advance.

I'd suggest you upgrade XCode to 4.6.3(latest). It is more stable than 4.6 — Amar

after downloading 4.6.3, is it neccessary to uninstall xcode 4.6 ? — Krunal

It will automatically be overwritten. Did you by any chance open your project with Xcode 5? — borrrden

In my case this was happening with Jenkins with an unmodified Xib file. Just relaunching the job fixed this...
