That makes sense. Do you keep the in-memory data in Racket data structures? I imagine keeping the data fed to Swift UI in sync with data maintained by GC'd Racket would involve some work.

Have you used https://github.com/Bogdanp/Noise? I assume serde would take up memory on both sides (Racket and Swift).

Sorry for a barrage of questions. I am quite curious about how all of this works. I am mulling over using OCaml for what you've used Racket for.
