You don't need to involve Objective-C to use a C API in Swift. You can call C functions directly in Swift and wrap them in a nice Swift API.

  I know that but if I decide to use Rust instead of Swift, why would I be wrapping Rust in Swift through C? And still it doesn't solve a problem how Rust can call anything from Cocoa or my existing code.

    Rust can call anything that exposes a C-compatible ABI, and Rust code can expose a C-compatible ABI so any language that can call into C (i.e. all languages) can call into Rust.

    > if I decide to use Rust instead of Swift, why would I be wrapping Rust in Swift through C? To avoid the unnecessary overhead of dynamically dispatched Objective-C method calls. To me, it seems more sensible to go Rust -> C -> Swift vs Rust -> C -> Objective-C -> Swift
