Segue from search results view controller to another view controller

There is a search controller with two scopes of decks and cards. I set up a search for these two models, but now the task is that when I tap on these results, for decks should be one segue for cards another. In the pictures, you can see, after I typed search text, it shows results correctly, but when you tap on the result row, nothing happens. Can't find any solution for almost a week...

class DecksTableViewController: UITableViewController {
	private var searchController: UISearchController!
	private var decks: Results<Deck>!

  override func viewDidLoad() {
    super.viewDidLoad()
		tableView.tableFooterView = UIView()
		let resultsTableController = self.storyboard?.instantiateViewController(withIdentifier: "ResultsTableViewController") as! ResultsTableViewController
		configureSearchController(resultsTableController)
		definesPresentationContext = true
		navigationItem.hidesSearchBarWhenScrolling = true
		navigationController?.navigationBar.prefersLargeTitles = true
  }
	
	override func viewWillAppear(_ animated: Bool) {
		super.viewWillAppear(animated)
		loadDecks()
	}
	
	private func loadDecks() {
		decks = StorageManager.realm.objects(Deck.self).sorted(byKeyPath: "dateCreated", ascending: true)
		tableView.reloadData()
	}
	
	private func configureSearchController(_ searchResultsController: ResultsTableViewController) {
		searchController = UISearchController(searchResultsController: searchResultsController)
		searchController.searchResultsUpdater = searchResultsController
		searchController.obscuresBackgroundDuringPresentation = false
		searchController.searchBar.placeholder = "Search"
		searchController.searchBar.scopeButtonTitles = ["Decks", "Cards"]
		searchController.searchBar.delegate = searchResultsController
		navigationItem.searchController = searchController
	}
}

Here the search results controller:

import UIKit
import RealmSwift


class ResultsTableViewController: UITableViewController {
	
	var filteredDecks: Results<Deck>?
	var filteredCards: Results<Card>?
	var scope: String?
	
  override func viewDidLoad() {
    super.viewDidLoad()
		tableView.delegate = self
		tableView.tableFooterView = UIView()
  }

  // MARK: - Table view data source

  override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
		if scope == "Decks" {
			return filteredDecks?.count ?? 0
		} else {
			return filteredCards?.count ?? 0
		}
  }
	

   
  override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "resultsCell", for: indexPath)
		var content = cell.defaultContentConfiguration()
		if scope == "Decks" {
			let deck = filteredDecks?[indexPath.row]
			content.text = deck?.name
		} else {
			let card = filteredCards?[indexPath.row]
			content.text = card?.front
			content.secondaryText = card?.back
		}
		
		cell.contentConfiguration = content
    return cell
  }
	
	override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
		if scope == "Decks" {
			guard let cardsVC = self.storyboard?.instantiateViewController(identifier: "cardsVC")
					as? CardsTableViewController
			else {
				return
			}
			cardsVC.selectedDeck = filteredDecks?[indexPath.row]
			self.parent?.navigationController?.pushViewController(cardsVC, animated: true)

		} else {
			guard let cardDetailVC = self.storyboard?.instantiateViewController(identifier: "cardDetailVC")
					as? NewCardViewController
			else {
				return
			}
			cardDetailVC.selectedCard = filteredCards?[indexPath.row]
			self.navigationController?.pushViewController(cardDetailVC, animated: true)
		}
		tableView.deselectRow(at: indexPath, animated: true)
	}
}


extension ResultsTableViewController: UISearchResultsUpdating {
	
	func updateSearchResults(for searchController: UISearchController) {
		let searchBar = searchController.searchBar
		let scope = searchBar.scopeButtonTitles![searchBar.selectedScopeButtonIndex]
		filterContentForSearchText(searchController.searchBar.text!, scope: scope)
	}
	
	private func filterContentForSearchText(_ searchText: String, scope: String) {
		
		var decks: Results<Deck>?
		var cards: Results<Card>?
		if scope == "Cards" {
			cards = StorageManager.realm.objects(Card.self).sorted(byKeyPath: "front")
			filteredCards = cards?.filter("front CONTAINS[c] '\(searchText)'")
		} else {
			decks = StorageManager.realm.objects(Deck.self).sorted(byKeyPath: "name")
			filteredDecks = decks?.filter("name CONTAINS[c] '\(searchText)'")
		}
		self.scope = scope
		tableView.reloadData()
	}
}

extension ResultsTableViewController: UISearchBarDelegate {
	
	func searchBar(_ searchBar: UISearchBar, selectedScopeButtonIndexDidChange selectedScope: Int) {
		filterContentForSearchText(searchBar.text!, scope: searchBar.scopeButtonTitles![selectedScope])
	}
