Add build support for Apple visionOS #131999
Description
Feature or enhancement
Proposal:
I've been using CPython in my iOS app successfully - but I need to bring my app to visionOS.
Happy to try adding support to the build myself - but I don't know the configure scripts very well. I do have hardware and would also be happy to test.
To be clear - not asking for any sort of specific support. Would just be happy to have build output for visionOS similar to tvOS/watchOS.
Has this already been discussed elsewhere?

FWIW - I have a patch adding tvOS and watchOS support. We had a recent contribution of a macCatalyst patch (see beeware/Python-Apple-support#117); that work that got close to being merged, but didn't quite get there before the contributor ran out of time to contribute. I expect the changes needed to add support for visionOS will essentially the same as those patches, substituting macCatalyst platform markers for visionOS/xros as appropriate.
The only additional changes that I would expect might be needed are:
config.subto correctly identify the visionOS compiler triple (it looks likearm64-apple-xrosandarm64-apple-xros-simulatoraren't currently supported); andI'm happy to act as a core team rep for any of these platforms (i.e., tvOS, watchOS, visionOS or macCatalyst); but I'm unlikely to have the volunteer time to develop the initial patches for visionOS and macCatalyst myself. I can probably find the resources to implement those patches if someone wants to fund the development of those patches; if that's an option you're interested in, reach out by email (my details are in my GitHub profile) and we can see what can be done.

FYI - thanks to contributions from @johnzhou721, https://github.com/beeware/Python-Apple-support now has the tooling in place to support building Python.framework for visionOS.
I haven't published any official builds yet, but the main branch is able to build a visionOS support package for CPython 3.14.0a7.

@freakboy3742 But two unit tests are failing.

@johnzhou721 I wasn't seeing any failures on my most recent test pass; If you're seeing an error, we can continue the discussion (and bug fixing) on Python-Apple-support

Closing the loop on this - the tests are passing, as long as you've updated your branch. There is a minor issue with the Makefile that produces build artefacts, which should be fixed shortly.

Woah - amazing! I wasn't prepared for this to be done so quickly - so my use case is still being held back by one other dependency before I can build. But happy to help test where I can.
