What does HackerNews think of swift-bridge?

swift-bridge facilitates Rust and Swift interop.

Language: Rust

A bit late, but swift-bridge (https://github.com/chinedufn/swift-bridge) does this intelligently, and is probably what you're looking for.
Got it - the other way is actually fine because Swift does have a stable ABI - swift-bridge [1] allows interop in terms of high level types instead of devolving to C.

Swift-based interop would provide richer type information. See how swift-bridge takes advantage of it:
