如何在swift中从相册中选择多个视频？

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    // ...
}

let imagePicker = UIImagePickerController()
imagePicker.sourceType = .photoLibrary

imagePicker.allowsMultipleSelection = true

imagePicker.delegate = self

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let selectedVideos = info[.mediaURL] as? [URL] {
        // 处理选择的视频
    }
    
    picker.dismiss(animated: true, completion: nil)
}

present(imagePicker, animated: true, completion: nil)
