ios - How to fix "Xcode quit unexpectedly while using the libclang.dylib plug-in."? -


i have every time in short while after start xcode (5.1.1).

removed user data, turned off source control (as posts suggested), no effect, still crashes (while showing indexing... never finishes). even reinstalled xcode, without effect, still says same.

did fixed such xcode?

or may find full crash report @ https://gist.github.com/eppz/10669132

there .m file in #import statement!

it caused 1 single line of code! can't belive it. stole 4 hours of figuring out. oh, combined @class statement.

it shows error, xcode / clang crashing faster can build. :d

the deadly pattern:

one.h

#import "two.m" // not easy spot actually.  @interface 1 : nsobject @end

two.h

@class one; @interface 2 : nsobject @property (nonatomic, weak) 1 *one; @end

i can't reproduce unless project mentioned on 200 classes. must kind of race-condition.
