I am a new ios developer and I am trying to use the media picker and default camera to record slow motion video. I am able to record video but it's 30 fps, not the 240 fps I want. Why doesn't the "slow-mo" option show up on the UI when the picker displays? How do I get that "slow-mo" option to show up like it does on the standard photo app? Is that the way this should work or is there a code-based approach to setting configuration that will allow for slow motion video to be recorded
