Question: Is GHC on iOS possible 2021?

[webmonarch]

I caught the bug of wanting to do some iOS development with Haskell and started down the rabbit hole of getting GHC compiled for iOS aarch64. I was starting from the post https://medium.com/@zw3rk/a-haskell-cross-compiler-for-ios-7cc009abe208

I am running into a number of "implicit function" errors when trying to compile 8.10.7. I tried tweaking some #if defined directives but the hole keeps getting deeper and my C and C tooling is woefully out of date.

Questions:

1. Is compiling GHC possible on iOS these days?
2. The blog post mentions a patched branch of GHC, but it doesn't look to exist any more
3. Opinion: How problematic do you think this path will be of Haskell compiling to aarch64 ios? Do you think PureScript in a JSContext would be smoother?

Thanks for the expertise!
