I don't find Swift to be an ergonomic systems language at all. I changed career paths soon after its introduction, focussing quite a bit on Clojure (and now begrudgingly Python) as I did not find value in its "safety" and much prefer ObjC's closeness to Posix and CoreFoundation libraries in the Apple ecosystem. Objective-C is bare bones and awkward indeed, but much more facile in interacting with system libraries. the typing dances required to utilize Swift in this low level context was absurd. I would probably investigate Zig first, and Rust second and even C++ long before Swift.
