What Hacker News says
4 sourcesThat 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.
In Show HN: I Made an iOS Podcast Player with RacketSure! I have a whole library dedicated to integrating Racket and Swift and you can find some of the nitty-gritty details there[1]. The gist of it is:
1. You build Racket for iOS in an interpreted mode (regular Racket works a bit like a JIT in that it needs to load code into memory at runtime, which is a no-go on iOS)
2. You link to it as a regular static library.
3. You call Racket's C API[2] to load and run Racket code.
Here's[3] a somewhat outdated video I did a while back on using that library for Mac app development. Many of the things in this video are now much simpler/more straightforward, but maybe it serves to give you an idea. I also have some source-available Mac apps built this way that you can take a look at[4, 5].

I've been doing similar things with Swift and Racket:
* https://defn.io/2023/03/19/racketfest-talk-2023/
* https://defn.io/2023/02/04/racket-foreign-callouts-to-swift/
I also started out using JSON to exchange data between the languages, but eventually wiring everything manually became an annoyance so I came up with a little Racket DSL[1] that automatically serializes and deserializes between the two languages (at runtime in Racket & using code generation in Swift). So far, I've built two apps with this approach, and I think it's great:

* https://github.com/Bogdanp/remember (macOS, iOS)
