The recent interview on Worse is Better mentioned that iOS restrictions on the use of JITs seem to be relaxing. I found this to be strategically significant so I brought it up with bytecode alliance (group promoting WASM standards). They seem to think it isn't going to happen. The change linked in the episode notes was in macos, and the requirements for distribution in iOS still seems to be dire. Dynamism is forbidden. You can write JITs for your iOS apps, but you can't distribute them unless they're only going to be run on a static input bundled with the app. https://bytecodealliance.zulipchat.com/#narrow/stream/206238-general/topic/.E2.9C.94.20using.20wit-bindgen.20in.20mobile.20rust

Oh that sucks! I totally missed the iOS / macOS distinction — doh. Thank you for looking into this and putting out the word.
