This PR addresses the comments with target_os specifics.

Tested it with Tier 3 target.

Thanks a lot! It's funny to think about this crate opening things in 3D ;).

Do you think it's common to just go with ios for visionos support? Is there some rationale?

[eugenehp]

visionOS has simulation for iOS apps out of the box. However it's flat, and not dimensional.
This crate will enable opening of AR models (USDZ, STL, GLTF) and regular URL links, and so on, including deep links.

If a dev hasn't done much with 3D (Unity, Swift, WebXR, WebGL, etc.) then it's probably easier just to use simulated iOS version, and not to worry about it.

Thanks for the clarification! Then I think it's fair to do it like this, with the option to add a dedicated visionos later should there be need.

Edit: And here it is the new release.
