I'm working on Valgrind on macOS, integrating Louis Brunner's work and trying to add a few more fixes. In 2025 support for macOS Intel 10.14, 10.15 11 and 12 was added. Intel macOS 13 is a bit harder of a nut to crack. And I have lots of issues with ARM, particularly building and testing on anything older that macOS 15. Swift name-mangling will be an issue. Valgrind's name demangler comes from GNU binutils libiberty which does not support Swift AFAIK.
