Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

Question

I’m having an issue to which I haven’t been able to find a solution just by searching here or on Google.

I’m building a project which is shared by multiple developer

Answer 1

Apparently, there's a corrupted .xib file. I reverted the file that was getting stuck compiling. I'm researching what's the line that's making it crash.

EDIT

I reproduced the problem in the console: There is a serious bug ongoing here.
