Cannot build on MacOS objc2::foundation not found

[mikedilger]

From 0xtr:

Yeah, several of them. E.g:

error[E0432]: unresolved import `objc2::foundation`
 --> /Users/oxtr/.cargo/registry/src/github.com-1ecc6299db9ec823/accesskit_macos-0.3.0/src/appkit/responder.rs:6:27
  |
6 | use objc2::{extern_class, foundation::NSObject, ClassType};
  |                           ^^^^^^^^^^ could not find `foundation` in `objc2`

All of them are related to the objc2 crate it seems, not sure which dependency this comes from though. Probably egui related dependencies?

I wanted to make a github issue for it but the error output is huge and contains my IRL name in the paths so I have to sanitize it before publishing it. Haven’t had time to do that today.

egui requires eframe requires egui-winit which requires accesskit_winit which requires accesskit_macos which is not building. The Cargo.lock requires version 0.3.0. A version 0.4.0 was released two days ago. cargo update could move it to 0.4.0 but might not fix the problem.

Probably this:

AccessKit/accesskit#199

I'm going to consider this closed. I think cargo update brought in a new version of accesskit_macos, which reverted to an older version of the objc beta.
