IOS app crashing only if installed from app store

I'm having a problem where if I run my app from installing it from the app store it's crashing (On multiple devices). But when I run the exact same code on the device from xCode it works fine.

I've been researching and the only suggestions I can find are to run in Release mode and change Optimization Level to fastest,smallest. Which I tried but it still doesn't crash. Heres the crash log I got:

I see that it doesn't like what I have on line 105 in XML.m, which is just a context save:

[context save:&saveError];

And like I said this line works just fine when I run it from xcode. Does anyone have any suggestions on how I can get more information on the exception or make this issue occur while debugging?

Thanks for any help.

EDIT: I watched the device log during the crash and found out the exception is "'NSInternalInconsistencyException', reason: 'This NSPersistentStoreCoordinator has no persistent stores. It cannot perform a save operation.'". Any idea as to why this is only happening from the app store?

Connect the device to Xcode or the iPhone configurations program and watch the log.

Also how looks the scope of the save statement. Is there a try catch around it? You have a NSError object that should have the info. Usualy it get logged using NSLog.

Edit:

Where get the store created path wise and has the device enough room to create the store?

I am taking a guess. Are you delivering the persistence store with your app? Lets say a sqllight database that is part of the app? You may read files from your app but never write to. You need to move the pre made persistence store to one of the directories you have write access.
