iPhone app crashes with coreData error

The first version of our app is in app store. In order to internationalize the app, one minor change has been to the core data model used by the app, the change being - a new attribute added to one of the entities.

I made the change by adding a new versioning model to the core data and by setting the current Core DataModel to this new version created.

In order to do a lightweight migration, I have added the required options as well like so:

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
    [NSNumber numberWithBool:YES],    NSMigratePersistentStoresAutomaticallyOption,
    [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
NSError *error = nil;
__persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]  initWithManagedObjectModel:[self managedObjectModel]];
[__persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error];

All this works fine when testing in the simulator and testing on the device ( when connected to MAC ). Once I made a ipa file and installed it on the device, the app crashes right when I start it. The default.png file shows up and then no other view is loaded.

The app crash log shows some issue with CoreData, but I am not able to put a finger and say this is what caused the problem. The crash log looks as below:

The line

"2 CoreData   0x324ee491 -[NSManagedObjectModel(_NSInternalMethods) _setIsEditable:] + 1" 

indicates some problem with the core data but I do not know what nor what I need to do to fix this. Any idea?

I found the issue after much time spent.

The ipa file was being built using a build script and this was caused by a build error.

The built .ipa file did not include the second version of core data. So the app always crashed.
