如何将Firebase数据从表视图单元格传递到视图控制器？

import UIKit
import Firebase

class TableViewController: UITableViewController {
    var firebaseData: [String] = [] // 用于存储Firebase数据的数组
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 从Firebase数据库中获取数据
        let ref = Database.database().reference()
        ref.child("data").observe(.value) { snapshot in
            if let data = snapshot.value as? [String] {
                self.firebaseData = data
                self.tableView.reloadData()
            }
        }
    }
    
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return firebaseData.count
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
        cell.textLabel?.text = firebaseData[indexPath.row]
        return cell
    }
    
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let selectedData = firebaseData[indexPath.row]
        
        // 创建目标视图控制器并传递数据
        if let destinationVC = storyboard?.instantiateViewController(withIdentifier: "DestinationViewController") as? DestinationViewController {
            destinationVC.data = selectedData
            navigationController?.pushViewController(destinationVC, animated: true)
        }
    }
}
