I'd be curious to hear more about these Swift features.

(Context: used to do iOS dev w/ obj-c; haven't used Swift, but keeping an eye on it, mostly out of curiosity.)

There was an interesting write up done recently about Swift ABI features that enable this and why Rust doesn't/can't do similar things due to different design goals.
