UISearchBar d'une chaîne dans un tableau

Question

J'essaye de créer une application de type de dictionnaire avec l'en-tête de section, le texte de titre, et le texte de sous-titre. J'ai réussi à tout faire fonctionner en utilisant le code suivant. La seule chose que je n'arrive pas à comprendre est comment filtrer l'UISearchBar pour montrer les résultats de la chaîne [Coptic] dans le tableau. Est-ce possible même de la façon dont j'ai organisé tout ou dois-je restructurer? Est-ce que quelqu'un a des suggestions?

J'ai laissé le code pour le updateSearchResults vide en bas parce que je ne sais pas quoi coder.

class Gamma: UITableViewController, UISearchBarDelegate, UISearchResultsUpdating { 


    struct words { 

     var sectionName : String! 
     var coptic : [String]! 
     var english : [String]! 
    } 

    var array = [words]() 
    var filtered = [words]() 
    var filtered2 = UITableViewController() 

    var indexarray = ["Ga", "Ge", "Gy", "Gn", "Go", "Gr", "Gw"] 

    let searchController = UISearchController(searchResultsController: nil) 




    override func viewDidLoad() { 
     super.viewDidLoad() 


     let defaultTextAttribs = [NSAttributedStringKey.font.rawValue: UIFont(name:"CS Avva Shenouda", size:17), NSAttributedStringKey.foregroundColor.rawValue:UIColor.black] 


     UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = defaultTextAttribs as Any as! [String : Any] 


     self.navigationController?.navigationBar.tintColor = UIColor.white 

     filtered = array 

     searchController.searchResultsUpdater = self 
     searchController.hidesNavigationBarDuringPresentation = false
