I am trying to implement my existing coredata project using the UITableViewDiffableDataSource. My tableview is coupled using the NSFetchedResultsController and the corresponding delegate methods. I am able to list the data in the tableview using diffabledatasource. My datasource is declared with the generic types as belowUITableViewDiffableDataSource<String, NSManagedObjectID>For enabling the editing mode in the tableview I subclassed the UITableViewDiffableDataSource. I can delete the cell from the tableview but not from my coreData. The code for deleting the cell is as belowoverride func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) { if editingStyle == .delete { if let identifierToDelete = itemIdentifier(for: indexPath){ var snapshot = self.snapshot() snapshot.deleteItems([identifierToDelete]) apply(snapshot) } }}The below NSFetchedResultsControllerDelegate method is not called when I delete the cell.func controller(_ controller: NSFetchedResultsController<NSFetchRequestResult>, didChangeContentWith snapshot: NSDiffableDataSourceSnapshotReference)I am not sure whether this is the correct way of coupling diffabledatasource with NSFetchedResultscontroller. Any help will be appreciated. Thanks in advance
