My comment was specifically about cross-platform. Apple operating systems don't know what spir-v is.

Oh well sure if you're targeting apple as a platform you're gonna have to deal with their special snowflake graphics API

I wish Apple had made a point to support Vulkan. I know about MoltenVK and all that fun stuff, but for a time, there was a graphics API that worked on all of the major platforms: OpenGL.

Vulkan was meant to succeed OpenGL, and despite my annoyances with the API, I still think that it's nice to have an open standard for these things, but now there isn't any graphics API that works on everything.
