I would expect the AVCaptureDevice.isStudioLightEnabled property to mirror the behaviour of AVCaptureDevice.isCenterStageEnabled however, I get the following exception when attempting to change it:
Thread 1: "*** +[AVCaptureDevice _setStudioLightEnabled:forcedSet:] May not be set when +studioLightControlMode == AVCaptureStudioLightingControlModeUser"
I can't seem to find any other reference to this studioLightControlMode property. I'd like to change it to AVCaptureStudioLightingControlModeApp like I can with AVCaptureCenterStageControlMode.
