Thanks for this. Have you tested this on visionOS hardware and in the simulator?

Thank you for the review. It's clearer now how ring works. The change is much simpler! And yes, I tested it; the app is even on the App Store :) .

Hello! I'm curious if this same change would be required to add support for watchos.

@QuentinPerez could you please rebase this on top of the latest changes on the main branch. The recent changes should result in it being even simpler now.

Hello! I'm curious if this same change would be required to add support for watchos.

There are several watchos targets, some of which are easier to support than others. PR #1914 started to add support for watchOS, but it got closed before it was finished. I suggest you pick where that left off.

What is the oldest cc-rs that is known to work for this? Because of issues like rust-lang/cc-rs#984 I'm weary of forcing users to update to too-new version of cc-rs right now, if we can avoid it.

VisionOS support was added in 1.0.93, but 1.0.94 includes a fix to how it integrates with xcrun that may be necessary. I don't see anything in the changelog after 1.0.94 related to visionos.
