How do i save video to new directory in ios?

I'm working with filemanager. So far I'm able to initialize my directory but when I try to save data there, the error i get is "error: Cannot create file".There seems to be an issue with the way I'm creating my path because when I use a temporary url, I am able to save to the photos library.

Here's the working temporary url code

var tempURL: URL? {
let directory = NSTemporaryDirectory() as NSString
if directory != "" {
  let path = directory.appendingPathComponent("video.mov")
  return URL(fileURLWithPath: path)
}
return nil

}

Here's the code where I execute the recording

  do {
      let videoPath = "SavedVideos"
      var videoDirectory = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
      videoDirectory = videoDirectory.appending(path: videoPath)
      videoDirectory = videoDirectory.appending(path: "000001")
      videoDirectory = videoDirectory.appending(path: "video.mov")
      movieOutput.startRecording(to: videoDirectory, recordingDelegate: self)
  }
  catch {
      print("error recording to video directory: \(error)")
  }

Again, changing startRecording(to:videoDirectory to startRecording(to: tempURL! , I able to record. Any insights on what I'm doing wrong?

The problem is that you add directories to the path (SavedVideos and 000001) without creating them , so Insert createDirectory like below

do {
    var videoDirectory = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
    videoDirectory = videoDirectory.appending(path: "SavedVideos/000001")
    try FileManager.default.createDirectory(atPath: videoDirectory.path, withIntermediateDirectories: true, attributes: nil)
    videoDirectory = videoDirectory.appending(path: "video.mov")
    movieOutput.startRecording(to: videoDirectory, recordingDelegate: self)
} catch {
    print(error.localizedDescription)
}
