获取的 URL 可能是一个相册中的资源标识符，需要通过 PHAsset 和 PHImageManager 来获取视频的实际 URL。可以在 `Coordinator` 类中添加一个方法来获取视频的 URL，然后在 `imagePickerController(_:didFinishPickingMediaWithInfo:)` 方法中调用该方法来获取实际的 URL。

具体实现如下：

final class Coordinator: NSObject, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
    // ...
    
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let assetIdentifier = info[.phAsset] as? String {
            getVideoURL(from: assetIdentifier) { url in
                if let url = url {
                    onURLPicked(url)
                }
            }
        }
        
        presentationMode.dismiss()
    }
    
    func getVideoURL(from assetIdentifier: String, completion: @escaping (URL?) -> Void) {
        let fetchResult = PHAsset.fetchAssets(withLocalIdentifiers: [assetIdentifier], options: nil)
        guard let asset = fetchResult.firstObject else {
            completion(nil)
            return
        }
        
        let options = PHVideoRequestOptions()
        options.version = .original
        
        PHImageManager.default().requestAVAsset(forVideo: asset, options: options) { avAsset, _, _ in
            guard let avAsset = avAsset else {
                completion(nil)
                return
            }
            
            let url = (avAsset as? AVURLAsset)?.url
            completion(url)
        }
    }
    
    // ...
}

这样获取到的 URL 就是实际的视频 URL，可以进行使用了。
