It is strange that your PR does not trigger the repo's workflow.

The macOS and Ubuntu is passing. But it will fail the compatibility test suite (which set OPENCOREGRAPHICS_COREGRAPHICS to 0 on macOS)

The error is

CGAffineTransformTests.swift:111:18: error: ambiguous use of 'init(a:b:c:d:tx:ty:)'

[Dark-Existed]

It now works with the compatibility test suite.

I've triggered the pipeline check. And I'll give a final review and merge this week if possible.
