In case you need a primer on using ARKit to display AR content with Metal (and who doesn’t?), we’ve got that too: https://developer.apple.com/documentation/arkit/displaying_an_ar_experience_with_metal …

Would you still recommend your Metal book as a primer on Metal, or would you recommend more up-to-date resources?

I mean, as someone who bought it back before it was free, I'm happy that I could support your work.

But as someone with limited spare time, who has yet to get past ch1, I'm worried that the API changes are going to be a major roadblock.

The changes (e.g. MetalKit) are additive and mostly reduce boilerplate, so everything should work out of the box if you’re using Obj-C.

Ah, okay, maybe my problem was that I was using Swift when I went through it before.
