如何在使用UISearchController时删除已排序/筛选的项目

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UISearchResultsUpdating {
    var tableView: UITableView!
    var searchController: UISearchController!
    var data: [String] = ["Apple", "Banana", "Cherry", "Durian", "Elderberry"]
    var filteredData: [String] = []
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView = UITableView(frame: view.bounds, style: .plain)
        tableView.dataSource = self
        tableView.delegate = self
        view.addSubview(tableView)
        
        searchController = UISearchController(searchResultsController: nil)
        searchController.searchResultsUpdater = self
        navigationItem.searchController = searchController
        navigationItem.hidesSearchBarWhenScrolling = false
    }
    
    // MARK: - UITableViewDataSource
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if searchController.isActive {
            return filteredData.count
        } else {
            return data.count
        }
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = UITableViewCell(style: .default, reuseIdentifier: nil)
        
        if searchController.isActive {
            cell.textLabel?.text = filteredData[indexPath.row]
        } else {
            cell.textLabel?.text = data[indexPath.row]
        }
        
        return cell
    }
    
    // MARK: - UITableViewDelegate
    
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
        
        if searchController.isActive {
            // Handle selected item in filteredData
            let selectedItem = filteredData[indexPath.row]
            // Remove selected item from filteredData
            filteredData.remove(at: indexPath.row)
            // Update original data array
            if let index = data.firstIndex(of: selectedItem) {
                data.remove(at: index)
            }
        } else {
            // Handle selected item in data
            let selectedItem = data[indexPath.row]
            // Remove selected item from data
            data.remove(at: indexPath.row)
        }
        
        tableView.reloadData()
    }
    
    // MARK: - UISearchResultsUpdating
    
    func updateSearchResults(for searchController: UISearchController) {
        let searchText = searchController.searchBar.text ?? ""
        
        filteredData = data.filter { $0.lowercased().contains(searchText.lowercased()) }
        
        tableView.reloadData()
    }
}
