Tableview cells are visible while app is in debug but when tried to terminate app and than try to reopen the app, cells are not visible.

Approach(Which i used in my app):

lazy var contactPickerScene: ContactTabelViewController = {
     guard let contactPickerScene = self.storyboard?.instantiateViewController(identifier: "ContactTabelViewController") as? ContactTabelViewController else {
        return ContactTabelViewController()
       }
      return contactPickerScene
      }()
contactPickerScene.contactDelegate = self
contactPickerScene.multiSelectEnabled = true
contactPickerScene.subtitleCellValue = .email
contactPickerScene.view.frame = self.contactListView.bounds
self.addChild(contactPickerScene)
self.contactListView.addSubview(contactPickerScene.view)
contactPickerScene.didMove(toParent: self)

public class ContactTabelViewController: UITableViewController, UISearchResultsUpdating, UISearchBarDelegate {

      ---------------------------
      public override func viewDidLoad() {
        super.viewDidLoad()

        // Uncomment the following line to preserve selection between presentations
        // self.clearsSelectionOnViewWillAppear = false

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
        // self.navigationItem.rightBarButtonItem = self.editButtonItem
        
        self.title = "Contacts"

        self.tableView.dataSource = self
        self.tableView.delegate = self
        
        inititlizeBarButtons()
        initializeSearchBar()
        registerContactCell()
        fetchContacts()
    }
    ---------------------------
}

// MARK: - Contact Operations
extension ContactTabelViewController {
    func fetchContacts() {
        DispatchQueue.global().async {
            self.getContacts( {(contacts, error) in
                if (error == nil) {
                    DispatchQueue.main.async(execute: {
//                        self.tableView.dataSource = self
//                        self.tableView.delegate = self
                        self.contactsList = contacts
                        self.tableView.reloadData()
                    })
                }
            })
        }
    }
    
    func getContacts(_ completion:  @escaping ContactsHandler) {
        if contactsStore == nil {
            contactsStore = CNContactStore()
        }
        let error = NSError(domain: "ContactPickerErrorDomain", code: 1, userInfo: [NSLocalizedDescriptionKey: "No Contacts Access"])
        
        switch CNContactStore.authorizationStatus(for: CNEntityType.contacts) {

i don't know why cellForRowAt is not getting called.
