Adds support for generating free-threaded and debug (and debug free-threaded) builds on iOS.

This is achieved by converting the checked-in testbed project into a template that includes {{abiflags}} references wherever the Python library (et al) is referenced. The initial clone of the testbed project makes the testbed "concrete" by filling in the appropriate {{abiflags}} content.

The build commands now include an --abiflags argument that allows t, d and td options; if those options are specified, the build is configured to disable GIL/enable debug as appropriate. This will produce a Python{T|D|TD}.xcframework, and the testbed bundled with the release artefact is rolled out to match the generated framework.

Also includes a GitHub Actions testing configuration.

Nice work!

It was fairly easy to update my iOS build script to instead build and test a free-threading build or a debug free-threading build.

FWIW, free-threading test run (M4 Pro):
Test Suite 'All tests' passed at 2026-10-14 00:57:17.732. Executed 1 test, with 0 failures (0 unexpected) in 758.194 (758.196) seconds

debug free-threading test run:
[...] in 1123.054 (1123.055) seconds

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot AMD64 CentOS9 Refleaks 3.x (tier-1) has failed when building commit d6f2129.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/#/builders/853/builds/4382) and take a look at the build logs.
  4. Check if the failure is related to this commit (d6f2129) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

https://buildbot.python.org/#/builders/853/builds/4382

Failed tests:

  • test.test_multiprocessing_fork.test_processes

Failed subtests:

  • test_interrupt - test.test_multiprocessing_fork.test_processes.WithProcessesTestProcess.test_interrupt

Hmm, this isn't the correct category, although maybe we should add sections for all support platforms (and one for unsupported?)?

iOS, Android, and Emscripten work has always been in a bit of an odd position with blurb - I would'nt object at all to an "other platforms" section in the docs (or however it ends up being spelled) as a better home for this sort of change.
