Resolved XCode 4.2.1 crash issues

Hi guys. I've recently started having some issues with XCode crashing when developing iOS apps. This hasn't been as a result of an update to XCode or OS X but I cannot recall what I have done to cause this problem.

Whenever I open the storyboard file in an iOS project, I get an error saying:
'Interface Builder Cocoa Touch Tool quit Unexpectedly'. (I'll attach full error logs at the end of the post). The same error pops up if I try to build the app as well.

Developing Mac Cocoa Applications however all runs without a hitch, no issue there.

It looks like I am missing several core frameworks for the iOS SDK. When I run the command

Code:

/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Xcode/Agents/Interface\ Builder\ Cocoa\ Touch\ Tool

from terminal I get the error message

Code:

dyld: Library not loaded: /System/Library/Frameworks/CoreText.framework/CoreText
  Referenced from: /Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Xcode/Agents/Interface Builder Cocoa Touch Tool
  Reason: image not found
Trace/BPT trap: 5

as well as the standard quit unexpectedly pop up.

I have tried:
- Completely removing XCode using sudo /Developer/Library/uninstall-devtools –mode=all
- Reinstalling XCode using the file on developer.apple.com instead of the App Store.
- Running the command sudo update_dyld_shared_cache -force
- Running the OS X 10.7.2 Combo update file.
- Manually searching for and placing the frameworks it complains that I am missing. This was working fine until it complained about one that I couldn't find.
- Changing my PATH to only include the unix paths (not brew/macports/fink ones).

Is there any way I can fix the missing frameworks without reinstalling OS X.

Obviously I've done something to make this suddenly start to malfunction. I thought it would be some C library (i.e. Boost) I've installed with Brew/MacPorts but I've removed those to no avail.

I really hope someone can help. If anyone else has experienced this issue and managed to solve it I would massively appreciate your input. I'm sure that a reinstall of OS X will solve the problem but that is a last resort.

Many thanks in advance,

Thanks the reply, appreciate your input. However I have already tried creating a new project, thus creating a new story board file. If you don't have it , then maybe my XCode is looking in the wrong place for it? Seeing as it does exist elsewhere (can't remember the exact path but a spotlight finds it).

Cheers,
Ollie

 

You, sir, are a god. I completely forgot about asepsis. I remove it using the uninstalled featured on its GitHub page and now Xcode is working perfectly.

Thank you so much!
