        var options = SceneKitVideoRecorder.Options.default

        let scale = UIScreen.main.nativeScale
        let sceneSize = sceneView.bounds.size
        options.videoSize = CGSize(width: sceneSize.width * scale, height: sceneSize.height * scale)
        recorder = try! SceneKitVideoRecorder(withARSCNView: sceneView, options: options)
    }
}

@IBAction func startRecording (sender: UIButton) {
  self.recorder?.startWriting().onSuccess {
    print("Recording Started")
  }
}

@IBAction func stopRecording (sender: UIButton) {
  self.recorder?.finishWriting().onSuccess { [weak self] url in
    print("Recording Finished", url)
  }
}

Performance tips

Here is a piece of Apple sample code

 if let camera = sceneView.pointOfView?.camera {
  camera.wantsHDR = true
  camera.wantsExposureAdaptation = true
  camera.exposureOffset = -1
  camera.minimumExposure = -1
}

The line camera.wantsHDR = true and camera.wantsExposureAdaptation = true causes a huge drop in video recording performance. You should remove or disable it for video recording.
