I get the wrong cell from the searchbar - swift

Question

var searchCountry = [String]() //to set up table
var searching = false
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
//table
extension DictionaryViewController: UITableViewDataSource, UITableViewDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if searching {
return searchCountry.count
} else {
return countrynameArr.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
if searching {
cell.textLabel?.text = searchCountry[indexPath.row]
} else {
cell.textLabel?.text = countrynameArr[indexPath.row]
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
myIndex = indexPath.row
performSegue(withIdentifier: "segue0", sender: self)
}
}
//Searchbar
extension DictionaryViewController: UISearchBarDelegate {
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
searchCountry = countrynameArr.filter({$0.lowercased().prefix(searchText.count) == searchText.lowercased()})
searching = true
tblView.reloadData()
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searching = false
searchBar.text = " "
tblView.reloadData()
}
}
Hello everyone, it is the first time I do programming so my codes are probably terrible :). I created a tableview and a searchbar. When I scroll down the tableview and click on a item I get the right cell. When I use the searchbar I will get a filtered list (that is perfect) but then..when I click on the third item of the filtered list I get the third item form the whole list. Can you please tell me my mistake?
