Kas CoreData tagabab turvalise töö mitme lõimega keskkonnas?

CoreData is not fully thread-safe. NSManagedObjectContext contexts cannot be used simultaneously from different threads.

To work safely in a multithreaded environment:

• Create a separate NSManagedObjectContext for each thread.
• Use the context type NSPrivateQueueConcurrencyType or NSMainQueueConcurrencyType.
• Perform operations with the context inside its perform or performAndWait blocks to ensure sequential access.

Thus, CoreData provides multithreading support through proper use of contexts and queues, but the developer must follow these rules to avoid thread safety issues.
