Whenever I try to run a specific project / app from Xcode it crashes with the details in the backtrace (please see below).
All sorts of funny stuff is going on running this in Xcode.
First, deleting the app from the iPad simulator and then running it for the first time seems to be working 90% of the time. But then either the second or the third attempt running on the iPad simulator it crashes again.
Trying to run it on a iPad device always crash, not luck at all.
Another funny thing I noticed is that whenever I do manage to get it to run for a second time on the iPad simulator all my appearance code (colors etc.) define in my app delegate is gone…
The only clue I could gather from the backtrace is: target ‘MyApp’ has been asked for its build context but it does not belong to a project
So, I’m not sure wheter this is Xcode related or perhaps somthing with the workspace / project file since it only crashes on this very specific project. If it is a problem with my workspace or project file, does anybody know how to fix this?
I appreciate your help.

So I finally figured out what the problem was.
I was using a build script that bumped my build number (CFBundleShortVersionString) after each build.
It seems Xcode doesn’t like the fact that the plist file gets changed underneath it.
The only “workaround” I could come up with was to remove the build step containing my version bump script that changed that plist file on every build.
