I used ObjectiveC on iOS but calling C from Swift is easy, especially
comparing it to JNI.

Thanks for the info everyone.
From Android, I am guessing you would use JNI to call LuaJIT, but what
about from Swift on iOS?

I made games that use LuaJIT for both Android and iOS. You won't have
problems related to CPU on Android and you shouldnt' have them on iOS
either. I made game that processes tens of thousands of objects in game
loop and it worked well, I think that you won't need more realtime
processing power than this game. You can check games here:

You can check other games on may accounts also, all of them use LuaJIT. I
ported one of games to windows phone where I had to use vanilla Lua and I
had some performance problems. LuaJIT is much faster even in just
interpreter mode so unless you do something really bad you shouldn't have
performance problems.

See http://luajit.org/running.html and http://luajit.org/install.html ;.
The former mentions that LuaJIT can run in interpreter only mode and the
latter mentions how to go about (cross) compiling for iOS and Android on
ARM (among other things). It also mentions there is no JIT on iOS but the
interpreter mode is still faster than vanilla Lua 5.x (not surprising,
LuaJIT is hand optimized ASM, vanilla Lua is pure and portable C code). The
wording ("Please complain to Apple, not me. Or use Android. :-p ") makes it
seem like there is proper JIT on Android without problems.

Sorry for the newbie question but I figured I get the fastest and most
accurate answer here:
1. Does LuaJIT run on both iOS and Android?
2. If yes to either, does it run any faster than standard Lua?
I ask these because I've heard that "executable memory" is not a feature
supported on these platforms so perhaps either LuaJIT won't work at all or
could be slower than Lua itself.
Thanks!
