Swift, while being slightly more friendly for extreme beginners than rust, is just so kneecapped and bloated that it has the opposite problem as rust. At some moderate level of competence it actively hinders learning. All of the weird closure and multithreading syntax is more harmful than good. Whereas Rust has a high floor and somewhat infuriating borrow checking, once you figure your way out of them you’ve actually learned a lot about how computers work along the way.
