Doesn't this break the policy of Apple? As I know, Apple allows apps only made of some restricted languages from when Adobe tried to make iOS apps with Flash.
The policy used to exist, it was Section 3.3.1 of the iOS Developer Agreement in 2010 [1]:
"Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs"
Steve Jobs also wrote some emails on the issue [2], but by September 2010 and following a potential Federal Trade Commission investigation, the clause had been removed again [3].
LuaJIT for iOS, confusingly, does not do JITing. Normal apps on iOS are unable to mark pages as executable, so it's impossible to JIT; it's not just an app store review-enforces restriction.
I did actually think that Apple required the use of Apple's developer tools for iThing apps --- so unless you can compile your target language into C, C++, ObjC (or Swift, I suppose) and then use XCode to compile the final binary, your app would be rejected. Has this changed?
Yeah, but it's still producing native code via a non-Apple toolchain. I'd want to check the T&Cs carefully, in case Apple notice and pull the app further down the line.
