User Profile

I have an ARSession using a ARWorldTrackingConfiguration as part of it's configuration. I've also enabled face tracking via configuration.userFaceTrackingEnabled = true. In the func session(_ session: ARSession, didUpdate frame: ARFrame) delegate method, I can successfully get the frame.capturedImage from the world-facing camera, but it doesn't seem like there's a way to access the frame from the face-facing camera. Am I correct in this assumption? If so, is there some other way to access the frames of both cameras when using face and world tracking together?

Is it possible to access a user-facing camera using AVFoundation while simultaneously running a world-tracking ARKit session? I know it's possible to do face-tracking while running a world-tracking session simultaneously, but I'm trying to just access the raw camera frames of the user-facing camera directly. From what it looks like, it seems that it's not possible to run an AVSession and ARSession simultaneously...when I try to do that with my code base, what ends up happening is only one camera is able to run.
