Search bar filtering wrong data - swift

Question

Disparately asking for your assistance
I am trying to filter Table View using search bar but the data I am getting is not in the correct position,
I tried several times to figure it out but without any chance, the result I am getting is only the first row does not matter which Room Number I am typing
I pasted the code below, your assistance is highly appreciated
final let urlString = "http://ccm-hotels.com/ccmandroid/api/getteams.php"
#IBOutlet weak var tableView: UITableView!
#IBOutlet weak var searchBar: UISearchBar!
#IBAction func BackToMenu(_ sender: UIBarButtonItem) {
let MainMenu = self.storyboard?.instantiateViewController(withIdentifier: "MainMenu") as! MainMenu
self.navigationController?.pushViewController(MainMenu, animated: true)
}
var openCaseRoomArray: [String] = []
var openCaseNameArray: [String] = []
var openCaseRoomArrayF: [String] = []
var inSearchMode = false
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
searchBar.delegate = self
searchBar.returnKeyType = UIReturnKeyType.done
openCaseRoomArrayF = openCaseRoomArray
let alertController = UIAlertController(title: nil, message: "Please wait\n\n", preferredStyle: .alert)
let spinnerIndicator = UIActivityIndicatorView(activityIndicatorStyle: .whiteLarge)
spinnerIndicator.center = CGPoint(x: 135.0, y: 65.5)
spinnerIndicator.color = UIColor.black
spinnerIndicator.startAnimating()
alertController.view.addSubview(spinnerIndicator)
self.present(alertController, animated: false, completion: nil)
let when = DispatchTime.now() + 5
DispatchQueue.main.asyncAfter(deadline: when){
// your code with delay
alertController.dismiss(animated: true, completion: nil);}
self.downloadJsonWithURL()
// Do any additional setup after loading the view, typically from a nib.

Answer 1

In your func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell method you are showing name from self.openCaseNameArray while you are updating your search result in self.openCaseRoomArrayF. When you are getting the api response you are assigning room and its corresponding name in your two arrays but when you are searching and updating your search result in self.openCaseRoomArrayF the index get changed. Now openCaseNameArray and openCaseRoomArray are in matched index but openCaseNameArray and openCaseRoomArrayF are not in same matched index. So you will not get the corresponding name in openCaseNameArray if you take room from openCaseRoomArrayF.
Try to make a Class (e.g Room) and store Room class object in a array. Search and show from that array. No need to maintain to array for this.
