Compile Erlang 24.2 for iOS on mac system

[Igor Clark]

Hello, I think I’m missing something key here! Does this mean Erlang/OTP is buildable on iOS now? If so, is there a way to bundle it inside an iOS app? Would it be possible even in theory to communicate with (let alone wrap any of) the iOS UI libs so that at least core logic can be in Erlang?

Last time I looked into doing any of that, it seemed like a hard “no”. Has that changed significantly and I’ve totally missed it? If none of the above, what’s the value of building on iOS?
