Search in TableView Swift 3 - Segue doesn't work when cell is clicked?

Question

iOS

Search in TableView Swift 3 - Segue doesn't work when cell is clicked. The reason, as I understand it, lies in the fact that the result is given in the resultController. But whatever I do segue doesn't work. Send POZZZHZH!

class TableViewController: UITableViewController, UISearchResultsUpdating {
    
    var searchController : UISearchController!
    var resultController = UITableViewController()
    var arFiltLet = [String]()
    
    var arLetter = ["Privet","test","А","Б","В","Г","Д","Е","Ж","З","И","Й","К","Л","М","Н","О","П","Р","С","Т","У","Ф","Х","Ц","Ч","Ш","Щ","Э","Ю","Я"]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        
        self.searchController = UISearchController(searchResultsController: self.resultController)
        self.tableView.tableHeaderView = self.searchController.searchBar
        self.searchController.searchResultsUpdater = self
        self.resultController.tableView.dataSource = self
        self.resultController.tableView.delegate = self
        definesPresentationContext = true
        
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.

    }
    func updateSearchResults(for searchController: UISearchController) {
       self.arFiltLet = self.arLetter.filter{(lett : String) -> Bool in
        if lett.lowercased().contains(self.searchController.searchBar.text!.lowercased()){
            return true
        }else{
            return false
        }
      }
        self.resultController.tableView.reloadData()
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if tableView == self.tableView {
            return self.arLetter.count
        }else{
            return self.arFiltLet.count
        }
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
       let cell = UITableViewCell()
        if tableView == self.tableView{
            cell.textLabel?.text = self.arLetter[indexPath.row]
        }else{
            cell.textLabel?.text = self.arFiltLet[indexPath.row]
        }
        return cell
    }
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        if segue.identifier == "segueTableToalpavitTable" && searchController.isActive {
            if let indexPath = self.resultController.tableView.indexPathForSelectedRow {
                let destanation = segue.destination as! AlphavitTableController
                destanation.letter = arFiltLet[(indexPath.row)]
            } else if let indexPath = self.tableView.indexPathForSelectedRow {
                let destanation = segue.destination as! AlphavitTableController
                destanation.letter = arLetter[(indexPath.row)]
            }
        }
        
        if segue.identifier == "segueTableToalpavitTable" {
            if let indexPath = self.tableView.indexPathForSelectedRow {
                let destanation = segue.destination as! AlphavitTableController
                destanation.letter = arLetter[(indexPath.row)]
            }
            
        }
    }
}

solution
let cell = self.tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
instead of
let cell = UITableViewCell()
