> I would absolutely not call Rust a simpler Swift. Swift doesn't have and ownership/borrowing system

Swift already does have those things but unlike Rust, they are opt-in.

Not going to argue which language is simpler, but sorry, you don't seem like someone who knows Swift very well.

While Swift now has the `borrowing` and `consuming` keywords, support for storing references is nonexistent, and the only way to return/store `Span`s, etc, is only possible through using experimental `@lifetime` annotations.

Swift is a nice language, and it's new support for the bare necessity of affine types is a good step forward, but it's not at all comparable with Rust.
