App Preview

       

we used NSFetchedResultsController of Core Data to Propagate data into TableView and

lazy var fetchResultController: NSFetchedResultsController<Team> = {

        let fetchRequest: NSFetchRequest<Team> = Team.fetchRequest()

        let sortTeamNameDescriptor = NSSortDescriptor(key: #keyPath(Team.teamName), ascending: true)
        let sortZoneDescriptor = NSSortDescriptor(key: #keyPath(Team.qualifyingZone), ascending: true)
        let sortScoreDescriptor = NSSortDescriptor(key: #keyPath(Team.wins), ascending: false)

        fetchRequest.sortDescriptors = [sortZoneDescriptor, sortScoreDescriptor, sortTeamNameDescriptor]

        let fetchResultController = NSFetchedResultsController(fetchRequest: fetchRequest, managedObjectContext: coreDataStack.managedContext, sectionNameKeyPath: #keyPath(Team.qualifyingZone), cacheName: "worldCup")
        fetchResultController.delegate = self
        return fetchResultController

    }()

Delegate methods of NSFetchedResultsControllerDelegate used into it

func controllerWillChangeContent(_ controller: NSFetchedResultsController<NSFetchRequestResult>) 

func controller(_ controller: NSFetchedResultsController<NSFetchRequestResult>, didChange anObject: Any, at indexPath: IndexPath?, for type: NSFetchedResultsChangeType, newIndexPath: IndexPath?)

func controller(_ controller: NSFetchedResultsController<NSFetchRequestResult>, didChange sectionInfo: NSFetchedResultsSectionInfo, atSectionIndex sectionIndex: Int, for type: NSFetchedResultsChangeType)
        
func controllerDidChangeContent(_ controller: NSFetchedResultsController<NSFetchRequestResult>)
