> I have a hard time understand what benefit Rust would give over swift

Rust is a drastically better-designed language, with substantially improved safety mechanisms, more advanced memory management (via lifetimes), generally better performance, and more powerful (generic) ADTs, to name a few things. That said, I'm not convinced it's better for the UI-centric development that Swift is targeting.

While I agree with you, to be fair to Swift it has other goals, and one primary one is to seamlessly work with existing objc, which it's excelled at.

> to be fair to Swift it has other goals

Exactly. If those are goals you share use Swift. If not, it may not be a good match.

So the question is valid: what benefit does one get using Rush over Swift on developing for Mac? Rust may be a better language overall, while still be an inferior choice in this context of Mac OS X Native app development.

I listed some of the benefits earlier in the thread. What I obviously can't do is prove it's better for native app development, because that depends on the developer.
