如何在同一个viewController中同时搜索和过滤tableViewCells？

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate {
    
    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var searchBar: UISearchBar!
    
    var data = ["Apple", "Banana", "Orange", "Grape", "Watermelon"]
    var filteredData = [String]()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView.dataSource = self
        tableView.delegate = self
        searchBar.delegate = self
    }
    
    // MARK: - UITableViewDataSource
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return filteredData.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
        cell.textLabel?.text = filteredData[indexPath.row]
        return cell
    }
    
    // MARK: - UISearchBarDelegate
    
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        filterData(with: searchText)
    }
    
    func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
        searchBar.text = ""
        filterData(with: "")
        searchBar.resignFirstResponder()
    }
    
    // MARK: - Helper Methods
    
    func filterData(with searchText: String) {
        if searchText.isEmpty {
            filteredData = data
        } else {
            filteredData = data.filter { $0.lowercased().contains(searchText.lowercased()) }
        }
        tableView.reloadData()
    }
}
