Apple reject my app because of not include functionality to allow users to view or select items from the Files app

问题

In my app I am get video from gallery using below method:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
}

But Apple is rejected app and required to include functionality to select video items from Files app.

Here is Apple give me the reason:

We noticed that your app enables users to view and select files, but it does not include functionality to allow users to view or select items from the Files app and the user's iCloud documents, as required by the App Store Review Guidelines.

It seems that they want you to use UIDocumentPickerViewController to enable users to select video files from cloud services as well as from the photo library in accordance with clause 2.5.15

Apple wants their customers to have a good experience with their device and the apps they run on it, so it makes sense for your app to support all relevant iOS features.

You can create a show a document picker to select video files using:

let picker = UIDocumentPickerViewController(documentTypes: ["public.movie"], in: .import)
picker.delegate = self
self.show(picker, sender: self)

You will need to implement some delegate code to handle the picked document. For example, to copy the selected file into your app's documents directory:

extension ViewController: UIDocumentPickerDelegate {
    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
        if let pickedUrl = urls.first {
            let filename = pickedUrl.lastPathComponent
            self.filename.text = filename
            let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
            var documentsDirectory = paths[0]
            // Apend filename (name+extension) to URL
            documentsDirectory.appendPathComponent(filename)
            do {
                // If file with same name exists remove it (replace file with new one)
                if FileManager.default.fileExists(atPath: documentsDirectory.path) {
                    try FileManager.default.removeItem(atPath: documentsDirectory.path)
                }
                // Move file from app_id-Inbox to tmp/filename
                try FileManager.default.moveItem(atPath: pickedUrl.path, toPath: documentsDirectory.path)
                UserDefaults.standard.set(filename, forKey:"filename")
                UserDefaults.standard.set(documentsDirectory, forKey:"fileurl")
                self.fileURL = documentsDirectory
            } catch {
                print(error.localizedDescription)
            }
        }
    }
}
