"Swift uses Automatic Reference Counting (ARC) to track and manage your app’s memory usage."

I meant 'not like rust-Arc' :)

... which is what I thought people were referring to.

Yes - it's ref counting, but it's not like 'Arc' at all - ARC is way more thread aware and most 'access' doesn't have to do thread checking. Much faster.

So - using Rust 'Arc' would not be at all like using Swift 'ARC' in the end.
