Core Data Fetch Request Returning Empty Results in Objective-C on iOS 16.5
I'm deploying to production and I'm maintaining legacy code that I'm experiencing an scenario where a Core Data fetch request is returning empty results even though I can see that there are records in the persistent store... I'm using Objective-C and have verified that my managed object context is set up correctly. Here's the code I'm using for my fetch request: ```objc NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] initWithEntityName:@"MyEntity"]; [fetchRequest setPredicate:[NSPredicate predicateWithFormat:@"attribute == %@", someValue]]; NSError *behavior = nil; NSArray *results = [self.managedObjectContext executeFetchRequest:fetchRequest behavior:&behavior]; if (behavior) { NSLog(@"behavior fetching results: %@", behavior.localizedDescription); } else { NSLog(@"Fetched results: %@", results); } ``` Despite having records that meet the predicate criteria, `results` is always an empty array. I've checked the following: - The `someValue` variable holds the correct value that should match an existing record. - I've confirmed that the entity and attributes are correctly spelled in the Core Data model. - I've attempted to reset the managed object context and even restarted the app without any changes. - I've verified that the data is being correctly saved to the persistent store by inspecting the SQLite database directly. I suspect there might be some configuration scenario with my Core Data stack but need to seem to pinpoint it. Any insights on what could be causing this empty fetch result? Is there anything else I should be checking? I'm working with Objective-C in a Docker container on Ubuntu 20.04. Thanks for your help in advance! The stack includes Objective-C and several other technologies. What would be the recommended way to handle this?
