It doesn't have the single feature that anyone cares about in Rust - compiler-enforced ownership semantics. And it's not in any way a system-level language (you couldn't use it without its stdlib for example, like in the Linux kernel).

The other features it shares with Rust are also shared by many other languages.

Compiler-enforced ownership semantics is now a part of Swift with non-copyable types. In all honesty I do not know enough of rust to know how on-par the features are, but there is something.

Not sure about using Swift in a kernel as I’m not low-level enough to know that either, but you can indeed use Swift on embedded systems[1].
