URL上的文件无法访问。将视频上传到Firebase存储-Swift

Question

已经5个小时了，我不知道为什么会收到此错误。

可选（“ URL上的文件：file：///private/var/mobile/Containers/Data/PluginKitPlugin/C6000DDA-6EE8-4DB3-A360-6DDE9EDCA730/tmp/trim.AD2C231C-65C6-4562- A332-39907709ECA0.MOV无法访问。“）

我有一个仅显示视频的照片选择器，我想将选择的视频上传到Firebase。我不知道为什么会收到此错误。我可以在不使用照片选择器的情况下上传任何视频，并且该视频可以正常运行，因此问题不在于firebase，而在于快速代码。

这是我的代码：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

if let pickedVideo = info[UIImagePickerController.InfoKey.mediaURL] as? NSURL {

        print("PICKED VIDEO")
        print("FIRST URL")
        print(pickedVideo)


        // try to upload here

        let url = URL(fileURLWithPath: pickedVideo.absoluteString!)

        print("NEW URL")
        print(url)

        let storageReference = Storage.storage().reference().child("upload")



                   // Start the video storage process
        storageReference.putFile(from: url , metadata: nil, completion: { (metadata, error) in
                       if error == nil {
                           print("Successful video upload")
                           storageReference.downloadURL { (url, error) in

                                   // Add a new document with a generated ID
                                   let db = Firestore.firestore()
                                   var ref: DocumentReference? = nil
                                   ref = db.collection("Posts").addDocument(data: [
                                   "caption": "self.CaptionTextField.text!",
                                   "isOnlyForMembers": "self.isOnlyForMembers!",
                                   "url": url!,
                                   "numberOfLikes": 0,
                                   "time": Timestamp(date: Date())
                                   ]) { err in
                                   if let err = err {
                                   print("Error adding document: \(err)")
                                   } else {
                                   print("Document added with ID: \(ref!.documentID)")
                                   db.collection("Posts").document(ref!.documentID).setData(["ID": ref!.documentID], merge: true)
                                  // self.activityIndi.stopAnimating()
                               //    self.performSegue(withIdentifier: "topostedsuccess", sender: self)


                                       }
                               }




                           }


                       } else {
                           print(error?.localizedDescription)
                       }
                   })




        }



    }
