Usage of `CGSRegionRelease` in `core-graphics` prevents publishing to the Mac AppStore

[wooden-worm]

My app got rejected from the Mac AppStore with the following message:

Guideline 2.5.1 - Performance - Software Requirements

Your app uses or references the following non-public or deprecated APIs:

Contents/MacOS/***
Symbols:
• _CGSRegionRelease

The use of non-public or deprecated APIs is not permitted on the App Store, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms.

I believe the offending code is here:

core-foundation-rs/core-graphics/src/private.rs

Line 24 in 0933af0

unsafe { ffi::CGSRegionRelease(self.region) }

I haven't found any workaround yet, any help would be greatly appreciated.

These were introduced in servo/core-graphics-rs#50.

There is no workaround other than not using the private APIs CGSRegion/CGSSurface anywhere in your code.

Perhaps you have a dependency somewhere that's using them? To find out, I'd suggest you clone the repo, remove the private module, and add the repo in a [patch.crates-io] section.

These were apparently only used in a long-dead, long-unused fork of glutin (servo-glutin).

I'm inclined to remove this functionality.

If that's true, I'm ok with that solution. How did you determine that?

[waywardmonkeys]

I searched for various things via GitHub code search and found that the only things using this were the code that it was specifically added for, in servo-glutin and various forks of it. I went to the upstream code and it appears that the code was never present there.
