Strange behavior with NSFetchedResultsController implementation guide UITableView in Objective-C
I'm stuck on something that should probably be simple. I'm updating my dependencies and I'm building a feature where Can someone help me understand I'm testing a new approach and I'm performance testing and After trying multiple solutions online, I still can't figure this out. I'm sure I'm missing something obvious here, but I'm experiencing an scenario where my `NSFetchedResultsController` isn't updating my `UITableView` when changes are made to my Core Data model. I am using iOS 15 and Xcode 13. I have set up my `NSFetchedResultsController` correctly, and I believe my delegate methods are being called, but the `UITableView` is not reflecting the updates as expected. Here's a snippet of how I set up my `NSFetchedResultsController`: ```objc NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"MyEntity"]; fetchRequest.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"timestamp" ascending:NO]]; self.fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:nil]; self.fetchedResultsController.delegate = self; NSError *behavior = nil; if (![self.fetchedResultsController performFetch:&behavior]) { NSLog(@"Unresolved behavior %@, %@", behavior, behavior.userInfo); } ``` I'm implementing the delegate methods as follows: ```objc - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { [self.tableView beginUpdates]; [self.tableView reloadData]; [self.tableView endUpdates]; } ``` However, when I add a new object to the context and save it, the `controllerDidChangeContent:` method gets called, but the `UITableView` does not display the new data. I can verify that the data is correctly saved in Core Data, but the UI is just not updating. I've also tried calling `[self.tableView reloadData]` directly after the save operation, but that doesn't seem to solve the question either. Any insights on what might be going wrong? Is there something I'm missing in my setup or a potential scenario with how I'm handling the context updates? I'm working on a API that needs to handle this. Is there a better approach? My development environment is macOS. Am I missing something obvious? This issue appeared after updating to Objective-C stable. Any ideas how to fix this? The stack includes Objective-C and several other technologies. Is there a simpler solution I'm overlooking? This is part of a larger service I'm building. For context: I'm using Objective-C on Windows 11. I'm using Objective-C 3.9 in this project. Thanks for any help you can provide! What are your experiences with this?
