UISearchBar and pass data to another view controller - swift

Question

There is table view to show phone contact and a search Bar in view controller . I implemented the code for the search-bar to filter givenName array it works just fine but when I click on the cell that I searched it doesn’t display the right information it displays only the information of the first row( exactly first index). The question it is how i can solve this problem ?
Data Model :
struct ContactStruct {
let identifier : String
let thumbnailImageData : UIImage
let givenName : String
let familyName : String
let phoneNumbers : String
let emailAddresses : String
}
Main View controller :
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
}
search bar methods:
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()
}
}

Follow just below code as an example :
let countriesList = ["African Union",
"Andorra",
"Armenia",
"Austria",
"Bahamas",
"Barbados",
"Belarus",
"Belgium",
]
#IBOutlet var tblPlace: UITableView!
#IBOutlet var searchPlace: UISearchBar!
var selctedCountries:[String] = []
var filteredData: [String]!
override func viewDidLoad() {
super.viewDidLoad()
searchPlace.delegate = self
filteredData = countriesList
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return filteredData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ApplyFilterTableViewCell", for: indexPath) as! ApplyFilterTableViewCell
cell.lblName = filteredData[indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let story = UIStoryboard(name: "Main", bundle: nil)
let vc = story.instantiateViewController(withIdentifier: "InsertContactViewController") as! InsertContactViewController
vc.strEditFitstName = filteredData[indexPath.row]
self.navigationController?.pushViewController(vc, animated: true)
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
filteredData = searchText.isEmpty ? countriesList : countriesList.filter({(dataString: String) -> Bool in
// If dataItem matches the searchText, return true to include it
return dataString.range(of: searchText, options: .caseInsensitive) != nil
})
tblPlace.reloadData()
}
