iOS上的可加载包,有什么办法可以实现这个目的吗？

import UIKit

class ViewController: UIViewController, XCAppExtensionNavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        if let url = Bundle.main.url(forResource: "example", withExtension: "html", subdirectory: "Documents") {
            let destinationUrl = URL(fileURLWithPath: NSHomeDirectory() + "/Documents/example.html")
            if let data = try? Data(contentsOf: url),
               let destination = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first {
                data.write(to: destination)
            }
        }
    }

    func launchAppExtension(_ url: URL) {
        if let sourceUrl = Bundle.main.url(forResource: "example", withExtension: "html", subdirectory: "Documents"),
           let data = try? Data(contentsOf: sourceUrl),
           let destinationUrl = URL(fileURLWithPath: NSHomeDirectory() + "/Documents/example.html") {
            data.write(to: destinationUrl)
        }
        
        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        appDelegate.launchOptions?[UIApplication.LaunchOptionsKey.extension] = url
        appDelegate.window?.makeKeyAndOrderFront(nil)
    }
}
