A tangent: does anyone have recommendations for a library for easy Swift-Rust interop? This is a cool tool, but I’d much rather make a GUI natively with e.g. SwiftUI and then call out to Rust for business logic. The previous times I’ve looked into this, both languages had to communicate through a C intermediate, and handling more complex types became a chore…

Mozilla's uniffi-rs is really good. You write a common IDL and the bindings are generated automatically. It supports Swift, Kotlin, Python, Ruby and JavaScript (not in the official repo).
