I wrote the code to search for values in the table, when I click on the search bar, the table disappears, but the value I need does not appear.
What could be the problem?
Update
var find: [List] = [] var searchResult: [List] = [] let context: NSManagedObjectContext = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext var detailViewController: MainVC? = nil var frc : NSFetchedResultsController = NSFetchedResultsController() var searchController: UISearchController! func getFetchResultsController() ->NSFetchedResultsController { frc = NSFetchedResultsController(fetchRequest: listFetchRequest(), managedObjectContext: context, sectionNameKeyPath: nil, cacheName: nil) return frc } func listFetchRequest() -> NSFetchRequest{ let fetchRequest = NSFetchRequest (entityName: "List") let sortDescriptor = NSSortDescriptor(key: "item", ascending: true) fetchRequest.sortDescriptors = [sortDescriptor] return fetchRequest } override func viewDidLoad() { super.viewDidLoad() frc = getFetchResultsController() frc.delegate = self do { try frc.performFetch() } catch {} if let split = self.splitViewController { let controllers = split.viewControllers self.detailViewController = (controllers[controllers.count-1] as!
