+         
+         Typical reasons for an error here include:
+         * The persistent store is not accessible;

+         
+         
+         If the persistent store is not accessible, there is typically something wrong with the file path. Often, a file URL is pointing into the application's resources directory instead of a writeable directory.
+         
+         If you encounter schema incompatibility errors during development, you can reduce their frequency by:
+         * Simply deleting the existing store:
+         [[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil]
+         
+         * Performing automatic lightweight migration by passing the following dictionary as the options parameter:
+         @{NSMigratePersistentStoresAutomaticallyOption:@YES, NSInferMappingModelAutomaticallyOption:@YES}
+         
+         Lightweight migration will only work for a limited set of schema changes; consult "Core Data Model Versioning and Data Migration Programming Guide" for details.
