Didselect делегат табличного представления после проблемы поиска в swift

Question

У меня есть контроллер представления и панель поиска над ним. эти данные, поступающие в табличном представлении, из службы. Я использовал фильтр поиска на нем. Элементы правильно ищутся, но когда я щелкаю ячейку, она открывает те же данные, что и перед поиском. Он снова и снова открывает одни и те же данные, а не открывает данные для этой фактической ячейки. Мой код для поиска в табличном представлении это,

 var filteredNames = [PostCodeModel]()
var isFiltering = false
var dishNameArray = [String]()
 func searchBarTextDidEndEditing(_ searchBar: UISearchBar) {
    isFiltering = false
}

func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
    isFiltering = false
}

func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
    isFiltering = true
}

func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
    isFiltering = false
}

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
    guard let searchText = searchBar.text else {
        isFiltering = false
        return
    }

    filteredNames = PostCodeService.instance.postCodeModelInstance.filter({
        return $0.name.lowercased().contains(searchText.lowercased())
    })

    isFiltering = filteredNames.count > 0
    self.restaurantTableView.reloadData()
}
extension RestaurantVC: UITableViewDelegate,UITableViewDataSource{

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if isFiltering {
        return filteredNames.count
    } else {
        return PostCodeService.instance.postCodeModelInstance.count
    }
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 200
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = restaurantTableView.dequeueReusableCell(withIdentifier: "restCell", for: indexPath) as! RestaurantListTableViewCell
    if isFiltering {
        cell.nameLbl.text = filteredNames[indexPath.row].name
        cell.descriptionLbl.text = filteredNames[indexPath.row].description
        cell.distanceLbl.text = filteredNames[indexPath.row].distance+"ml"
        cell.minOrderLbl.text = String(filteredNames[indexPath.row].minimum_spending)
        cell.deliveryLbl.text = String(filteredNames[indexPath.row].delivery_time) + "min"
        cell.discountLbl.text = "20%off"
        let nameImage = filteredNames[indexPath.row].icon_name
        cell.restaurantImage.sd_setImage(with: URL(string: nameImage!), placeholderImage: UIImage(named: "placeholder.png"))
        latitude = Double(filteredNames[indexPath.row].latitude)!
        longitude = Double(filteredNames[indexPath.row].longitude)!

        latitudeArray.append(latitude)
        longitudeArray.append(longitude)
        nameArray.append(cell.nameLbl.text!)

        let defaults = UserDefaults.standard
        defaults.set(latitudeArray, forKey: "latitudeArray")
        defaults.set(longitudeArray, forKey: "longitudeArray")
        defaults.set(nameArray, forKey: "nameArray")
        defaults.synchronize()

        cell.selectionStyle = .none
        cell.backgroundColor = UIColor.clear
        return cell
    } else {
    cell.nameLbl.text = PostCodeService.instance.postCodeModelInstance[indexPath.row].name
    cell.descriptionLbl.text = PostCodeService.instance.postCodeModelInstance[indexPath.row].description
    cell.distanceLbl.text = PostCodeService.instance.postCodeModelInstance[indexPath.row].distance+"ml"
    cell.minOrderLbl.text = String(PostCodeService.instance.postCodeModelInstance[indexPath.row].minimum_spending)
    cell.deliveryLbl.text = String(PostCodeService.instance.postCodeModelInstance[indexPath.row].delivery_time) + "min"
    cell.discountLbl.text = "20%"+"Off"
    let nameImage = PostCodeService.instance.postCodeModelInstance[indexPath.row].icon_name
    cell.restaurantImage.sd_setImage(with: URL(string: nameImage!), placeholderImage: UIImage(named: "placeholder.png"))

    latitude = Double(PostCodeService.instance.postCodeModelInstance[indexPath.row].latitude)!
    longitude = Double(PostCodeService.instance.postCodeModelInstance[indexPath.row].longitude)!

    latitudeArray.append(latitude)
    longitudeArray.append(longitude)
    nameArray.append(cell.nameLbl.text!)

    let defaults = UserDefaults.standard
    defaults.set(latitudeArray, forKey: "latitudeArray")
    defaults.set(longitudeArray, forKey: "longitudeArray")
    defaults.set(nameArray, forKey: "nameArray")
    defaults.synchronize()

    cell.selectionStyle = .none
    cell.backgroundColor = UIColor.clear
    return cell
    }
}

func filterContentForSearchText(_ searchText: String, scope: String = "All") {
    filteredNames = PostCodeService.instance.postCodeModelInstance.filter({
        return $0.name.lowercased().contains(searchText.lowercased())
    })

    restaurantTableView.reloadData()
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
  if isFiltering {
    let resId = String(filteredNames[indexPath.row].resId)
    print(resId)
    UserDefaults.standard.set(resId, forKey: "restaurantId")
    UserDefaults.standard.set(resId, forKey: "resID")
    UserDefaults.standard.synchronize()
    let name = filteredNames[indexPath.row].name
    let resImage = filteredNames[indexPath.row].icon_name
    let description = filteredNames[indexPath.row].description
    let minOrder = String(filteredNames[indexPath.row].minimum_spending)
    let deliveryTime = String(filteredNames[indexPath.row].delivery_time)

    UserDefaults.standard.set(name, forKey: "name")
    UserDefaults.standard.set(description, forKey: "description")
    UserDefaults.standard.set(minOrder, forKey: "minOrder")
    UserDefaults.standard.set(minOrder, forKey: "deliveryTime")
    UserDefaults.standard.set(resId, forKey: "resId")

    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: "RestaurantMenuVC") as! RestaurantMenuVC

    vc.resId = resId
    vc.name = name!
    vc.restImage = resImage!
    vc.resDesc = description!
    vc.minOrder = minOrder
    vc.deliveryTime = deliveryTime

    self.navigationController?.pushViewController(vc, animated: true)
    }
    else
  {
    let resId = String(PostCodeService.instance.postCodeModelInstance[indexPath.row].resId)
    print(resId)
    UserDefaults.standard.set(resId, forKey: "restaurantId")
    UserDefaults.standard.set(resId, forKey: "resID")
    UserDefaults.standard.synchronize()
    let name = PostCodeService.instance.postCodeModelInstance[indexPath.row].name
    let resImage = PostCodeService.instance.postCodeModelInstance[indexPath.row].icon_name
    let description = PostCodeService.instance.postCodeModelInstance[indexPath.row].description
    let minOrder = String(PostCodeService.instance.postCodeModelInstance[indexPath.row].minimum_spending)
    let deliveryTime = String(PostCodeService.instance.postCodeModelInstance[indexPath.row].delivery_time)

  UserDefaults.standard.set(name, forKey: "name")
  UserDefaults.standard.set(description, forKey: "description")
  UserDefaults.standard.set(minOrder, forKey: "minOrder")
  UserDefaults.standard.set(minOrder, forKey: "deliveryTime")
  UserDefaults.standard.set(resId, forKey: "resId")

            let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: "RestaurantMenuVC") as! RestaurantMenuVC

    vc.resId = resId
    vc.name = name!
    vc.restImage = resImage!
    vc.resDesc = description!
    vc.minOrder = minOrder
    vc.deliveryTime = deliveryTime

    self.navigationController?.pushViewController(vc, animated: true)
    }

}

}

Я разместил проверку для отфильтрованных данных, но она всегда показывает одни и те же результаты каждый раз, когда я нажимаю на результат поиска.
