, reason=Can't find model for source store}'

It says can't find model for source store? What does this mean?

The code is:

- (void)createPersistentStoreCoordinator {
    NSURL *storeUrl = [NSURL fileURLWithPath:self.pathToStoreFile];

    NSError *error;
    _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:_managedObjectModel];

    // Allow inferred migration from the original version of the application.
    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                             [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
                             [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];

    if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) {
        if (self.delegate != nil && [self.delegate respondsToSelector:@selector(managedObjectStore:didFailToCreatePersistentStoreCoordinatorWithError:)]) {
            [self.delegate managedObjectStore:self didFailToCreatePersistentStoreCoordinatorWithError:error];
        } else {
            NSAssert(NO, @"Managed object store failed to create persistent store coordinator: %@", error); //fails right here
        }
    }
}

I noticed you are using RestKit, and I had this problem before, and solved it by removing my SqlLite database. For me, it was when I added a new relationship and the database didn't like the new attribute.

Note: this works fine in development, but in Production you will need to perform a Core Data migration usually, as users won't want their data lost (depending on your application).

Yes, I agree with firetoast. The problem disappears for me when I simply delete my application from the device/emulator and reinstall. This normally happens to me after I edit my core data schema and use restkit to persist.

Things you should check:

• Be sure you have loaded your context correctly, and the .momd file is added to your app bundle
• Be sure your entity is named 'store' in the datamodel visual editor

Also, when dealing with CoreData there is a interesting userinfo which holds much useful informations:

NSDictionary *ui = [error userInfo];
        for(NSString *err in [ui keyEnumerator]) {
            NSLog(@"err:%@",[ui objectForKey:err]);
        }

NSAssert is doing an assertion on whether or not a statement is true. By passing in NO to it, you are making it so that it will always fail the assertion check. I am assuming this is to force a hard fail if the previous if statement is false.
