Assuming that the `mach2` crate is updated to support these platforms, or we get rid of that dependency.
Required for `extern "C-unwind"`.

Thank you for this work and your work on the objc2 crates!
This sounds good to me.
FYI:
Yocto kirkstone (Rust 1.59.0) goes into EOL on April 2026.
The next supported release is Scathgap, which will have Rust 1.75.0.

Use
objc2-io-kitandobjc2-core-foundationinstead ofio-kit-sysandcore-foundation.These are part of the
objc2project which I maintain, which provides auto-generated bindings for Apple's APIs. This allows us to be much more confident that the bindings are correct, handles memory management likeCFRetain/CFReleaseautomatically, allows us to do cool things like embedding documentation from the headers.Note also that
core-foundationhas been soft-deprecated in favour ofobjc2-core-foundation, see servo/core-foundation-rs#729, so it makes sense to start this migration.This builds upon #260, so that should probably be merged first. This change also requires an MSRV bump to 1.71 because these crates use
extern "C-unwind", so this should probably be put in thev5.0.0milestone IIUC, see also #231.
