This is just quibbling, but 1) you can write Metal code with Swift as well as Objective-C (and that's not even vendor-locked; I'm doing Swift in Linux right now), and 2) you can write C++ in Objective-C.

I know this isn't what you're really complaining about, though.

You mean Objective-C++.

The most common pattern I've seen with cross-platform stuff is a small Objective-C wrapper over MacOS APIs, which then gets called like C functions from pure C++ code.
