He/She was talking about developer ergonomics. And in that particular sense, while i have programmed in Swift and Rust, i completely agree with him/her.

In your disagreement you are pointing out how you think Rust is more _advanced_ than Swift. But this goes into a tangential topic, that was not what the parent was pointing out.

In developer productivity and ergonomics Rust is not far away from C++, and Swift is more akin to Kotlin, C# and Java, but it feels a little better like Typescript or Dart.

I wonder, why, so many times, Rust folks (Why to get tied to a tech, i also don't get it) gets so hostile and arrogant about the language, and to be fair this is some of the reasons i keep a certain distance from it, and i can imagine that im not the only one.
