## Discussion

Discussion Invoking this method causes the persistent container to create and return a new NSManagedObjectContext with the concurrencyType set to NSManagedObjectContextConcurrencyType.privateQueueConcurrencyType. This new context will be associated with the NSPersistentStoreCoordinator directly and is set to consume NSManagedObjectContextDidSave broadcasts automatically.
