--- Comment #16 from Ivan Enderlin <ivan at mnt.io> ---
Mark,

I can't use a `WKWebView` because I need my Wasm module import functions to be defined as JS callbacks, so that I can implement them in Rust. As far as I know, it's not possible to pass `Function` objects from the “host” to a `WKWebView` via `postMessage`. Is there a safe way to achieve that maybe?

I'm sorry but… before running into this project, we have tested running Wasm on iOS and it was working great via JSC. 2 persons have tested it on 2 different devices, and we have seen the same thing: Wasm was running on iOS via JSC. 

Anyway, is there a chance that we will be able to run Wasm in a short-future without JIT, only purely with LLInt? Or is there a chance that JIT will be enabled inside JSC C API? Do you have a public roadmap about that topic?

Thanks.
