I'm trying to make a tableView of cards in a deck that have two scopes Questions and Rating.

this is my code:

<pre lang="Swift">
import UIKit

class DeckTableViewController: UITableViewController,  UISearchBarDelegate {
    
    static let displayCardSegueID = "displayCard"
    
    @IBOutlet weak var searchBar: UISearchBar!
    
    var originalData = [Card]()
    var filteredData = [Card]()
    
    let searchController = UISearchController(searchResultsController: nil)

    
    //MARK: Search Bar
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        filteredData = originalData.filter({ Card -> Bool in
            switch searchBar.selectedScopeButtonIndex {
            case 0:
                if searchText.isEmpty { return Card.question == Card.question }
                return Card.getQuestion().lowercased().contains(searchText.lowercased()) &&
                    Card.getQuestion() == Card.question
            case 1:
                if searchText.isEmpty { return Card.getRating() == Card.rating }
                return Card.getRating().lowercased().contains(searchText.lowercased()) &&
                    Card.getRating() == Card.rating
            default:
                return false
            }
        })
        tableView.reloadData()
    } //textDidChange
    
    func searchBar(_ searchBar: UISearchBar, selectedScopeButtonIndexDidChange selectedScope: Int) {
        switch selectedScope {
        case 0: filteredData = originalData.filter( {Card -> Bool in
                        Card.getQuestion() == Card.question })
        case 1: filteredData = originalData.filter( {Card -> Bool in
                        Card.getRating() == Card.rating })
        default: break
        } // switch
        tableView.reloadData()
    }

    // MARK: something idk
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // searchController.searchBar.scopeButtonTitles = ["Questions", "Rating"]
       // searchController.searchBar.delegate = self
        /*
        if let savedDeck = loadDeck() {
            originalData += savedDeck
        } else {
            startingCards()
        }
        */
        startingCards()
        filteredData = originalData
        // startingCards()
        SharedDeck.loadDeck()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func unwindToDeckList(sender: UIStoryboardSegue) {
        if let sourceViewController = sender.source as? AddCardViewController
        {
            if let newCard = sourceViewController.getCard() {
                let deck = SharedDeck.getDeck()
                
                let newIndexPath = IndexPath(row: deck.getSize(), section: 0)
                deck.appendCard(card: newCard)
                tableView.insertRows(at: [newIndexPath], with: .automatic)
            }
        }
    }
    
    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return SharedDeck.getDeck().getSize()
        
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        guard let cell = tableView.dequeueReusableCell(withIdentifier: "CardTableViewCell", for: indexPath) as? CardTableViewCell else {
            fatalError("The aquired cell is not a CardTableViewCell")
        }

        // Get the appropriate card from the deck
        let currentCard = SharedDeck.getDeck().getCardAt(index: indexPath.row)
        
        // Set the cell properties
        cell.cellImageView.image = currentCard.getImage()
        cell.cellQuestionLabel.text = currentCard.getQuestion()
        cell.cellRatingLabel.text = currentCard.getRating()

        return cell
    }

    // Override to support conditional editing of the table view.
    override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        // Return false if you do not want the specified item to be editable.
        return true
    }

    // Override to support editing the table view.
    override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
        if editingStyle == .delete {
            SharedDeck.getDeck().deleteCardAt(index: indexPath.row)
            // Delete the row from the data source
            tableView.deleteRows(at: [indexPath], with: .fade)
        }
    }

    func startingCards() {
        guard let q1 = Card(question: "what starts with r?", answer: "red", image: UIImage(named: "red"), rating: "1")
            else {
                fatalError("Unable to instantiatie card")
            }
        
        //originalData.append(q1)
        
        guard let q2 = Card(question: "what starts with a?", answer: "apple", image: UIImage(named: "apple"), rating: "3")
            else {
                fatalError("Unable to instantiatie card")
            }
        
        //originalData.append(q2)
        
        guard let q3 = Card(question: "what starts with q?", answer: "quit", image: UIImage(named: "quit"), rating: "2")
            else {
                fatalError("Unable to instantiatie card")
            }
        
        //originalData.append(q3)
        originalData += [q1, q2, q3]
        
    }

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == DeckTableViewController.displayCardSegueID {
            CardViewController.setCard(card: SharedDeck.getDeck().getCardAt(index: (tableView.indexPathForSelectedRow?.row)!))
        }
    }
}

What I have tried:

when i run it, i see the search bar and the two scopes, however when i type in the search bar nothing happens, i guess its not even searching anything, and when i select a scope it doesn't do anything either.

Also none of my startingCards show up either not sure why.
