在表控制器中有显示电话联系的表格视图和搜索栏。我实现了用于搜索栏的代码来过滤namedName数组，它的工作原理很好，但是当我单击所搜索的单元格时，它没有显示正确的信息，它仅显示了第一行的信息（恰好是第一个索引）。问题是我该如何解决这个问题？

数据模型：

struct ContactStruct {
    let identifier : String
    let thumbnailImageData : UIImage
    let givenName : String
    let familyName : String
    let phoneNumbers : String
    let emailaddresses : String
}

主视图控制器：

        class NewContactViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {

         var contactsData = [ContactStruct]()
         var searchedContact = [String]()
         var searching = false

       @IBOutlet weak var tblMain: UITableView!
       @IBOutlet weak var contactSearchBar: UISearchBar!

       override func viewDidLoad() {
          super.viewDidLoad()
    }

       func tableView(_ tableView: UITableView,didSelectRowAt indexPath: IndexPath) {
          let story = uistoryboard(name: "Main",bundle: nil)
          let vc = story.instantiateViewController(withIdentifier: "InsertContactViewController") as! InsertContactViewController
          vc.strEditFitstName = contactsData[indexPath.row].givenName
          vc.stridentifier = contactsData[indexPath.row].identifier
          self.navigationController?.pushViewController(vc,animated: true)
       } 

 func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
      if searching {
         return searchedContact.count
      } else {
         return contactsData.count
      }
   }
   func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
      let cell = tableView.dequeueReusableCell(withIdentifier: "testCell") as! NewContactCell
      let contactToDisplay = contactsData[indexPath.row]
   contactToDisplay.familyName
      cell.lblLName.text = contactToDisplay.givenName

      return cell
   }

搜索栏方法：

extension NewContactViewController: UISearchBarDelegate {
   func searchBar(_ searchBar: UISearchBar,textDidChange searchText: String) {
      let givenNames = contactsData.map { $0.givenName }
      searchedContact = givenNames.filter({$0.lowercased().prefix(searchText.count) == searchText.lowercased()})
      searching = true
      tblMain.reloadData()
   }
   func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
      searching = false
      searchBar.text = ""
      tblMain.reloadData()
   }
}
