What to learn next, Swift or Rust (lemmy.world)

I’ve been programming for decades, though usually for myself, not as a profession. My current go-to language is Python, but I’m thinking of learning either Swift (I’m currently on the Apple ecosystem), or Rust. Which one do you think will be the best in terms of machine learning support in a couple of years and how easy is it to build MacOS/ iOS apps on Rust?

Thanks for sharing the interview with Lattner; that was quite interesting.

I agree with everything he said. However, I think you're either misinterpreting or glossing over the actual performance question. Lattner said:

The performance side of things I think is still up in the air because ARC certainly does introduce overhead. Some of that’s unavoidable, at least without lots of annotations in your code, but also I think that ARC is not done yet. A ton of energy’s been poured into research for garbage collection... That work really hasn’t been done for ARC yet, so really, I think there’s still a a big future ahead.

That's optimistic, but certainly not the same as saying there are no scenarios in which GC has performance wins.
