You can use shouldChangeTextIn Delegate method of UISearchBar.

  func searchBar(_ searchBar: UISearchBar, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {

    let newCharLength = (searchBar.text ?? "").characters.count + text.characters.count - range.length

    if newCharLength.count > 0 {

        arrSearchFilter = arrNames.filter { (str) -> Bool in
                    return (str.lowercased().contains((searchBar.text?.lowercased())!))!
                }

             if arrSearchLocalityModel.count > 0 {
                    arrSearchLocality = arrSearchLocalityModel
                } else {
                    arrSearchLocality = arrLocalityModel
                }

          self.tableView.reloadData()

        }


    }

From the question I believe you are performing the search correctly but you want to get the word/text which is entered in the searchBar to perform the search. We will get the text entered in searchBar using the searchBar.text property of UISearchBarController

Try

let searchToSearch = searchController.searchBar.text
