如何使用API中的数据搜索tableview？

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    
    var tableView: UITableView!
    var data = [Item]()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView = UITableView(frame: view.bounds, style: .plain)
        tableView.dataSource = self
        tableView.delegate = self
        view.addSubview(tableView)
        
        fetchData()
    }
    
    func fetchData() {
        let url = URL(string: "https://api.example.com/items")!
        let task = URLSession.shared.dataTask(with: url) { data, response, error in
            if let error = error {
                print("Error fetching data: \(error)")
                return
            }
            
            guard let data = data else { return }
            
            do {
                let items = try JSONDecoder().decode([Item].self, from: data)
                DispatchQueue.main.async {
                    self.data = items
                    self.tableView.reloadData()
                }
            } catch {
                print("Error decoding JSON: \(error)")
            }
        }
        
        task.resume()
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return data.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = UITableViewCell(style: .subtitle, reuseIdentifier: "cell")
        let item = data[indexPath.row]
        cell.textLabel?.text = item.title
        cell.detailTextLabel?.text = item.description
        return cell
    }
}

struct Item: Codable {
    let title: String
    let description: String
}
