    @IBOutlet weak var TableView: UITableView!

    var data = [ "one", "two"]

    var filteredData = [String]()

    var inSearchMode = false

    override func viewDidLoad() {
        super.viewDidLoad()
        TableView.delegate = self
        TableView.dataSource = self
        searchBar.delegate = self
        searchBar.returnKeyType = UIReturnKeyType.done
        // Do any additional setup after loading the view.
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

            if inSearchMode {

                text = filteredData[indexPath.row]

            filteredData = data.filter({$0.contains(searchBar.text!)})

            TableView.reloadData()
        }
    }
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
    {
        IndexC = indexPath.row
        performSegue(withIdentifier: "segue", sender: self)

You can try

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
 {
     var text = ""

    if inSearchMode {

        text = filteredData[indexPath.row]

        let correctIndex = data.index(of:filteredData[indexPath.row])

        print("selected value is : \(correctIndex)")


    } else {

        text = data[indexPath.row]
    }


    performSegue(withIdentifier: "segue", sender: text)
 }
 override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
     if let secondController = segue.destination as? SecondController {
         secondController.sendedValue =  sender as! String
     }
 }

 class secondController:UIViewController
 {
   var sendedValue:String?
 }

Issue is here:

Name.text = NamesC[IndexC]

Your array is filtered, your indexC is the one you used in the filtered array.

You can define a filtered array FNamesC, and update this array when you search in your search bar and in your viewController

Name.text = FNamesC[IndexC]

I don't know why you want a global array though.
