Is there a definitive answer for any camera output availability for 3rd party apps in VisionOS used on Apple Vision Pro? Official video (below) is inconclusive as it advices AVCaptureDevice.DiscoverySession to check for available camera devices while XCODE says such function is not available in VisionOS. The alternative could be a stream of visible content turned into some buffer. Is it possible? LINK: https://developer.apple.com/videos/play/wwdc2023/10094/?time=588
At present, no. Hopefully they will reconsider that in the future, because the lack of sensor data is extremely limiting to AR apps that are aware of the environment.
As is, it would not be possible to have an app that can assist a car mechanic by looking at an engine, identifying what model it is, and walking them through removal or disassembly.
We wouldn't be able to use a Golf Swing Analyzer to help a coach analyze form and performance, or make recommendations on how to improve.
Tools like Brickit can't look at leftover pieces, figure out a plan for them, and help you locate them amidst the pile.
Lack of sensor data means that in many ways, Vision Pro is less capable as an AR device than an iPhone.
