These days, there are plenty of other frameworks for writing native iOS apps in languages other than Obj-C&#x2F;Swift (Xamarin&#x2F;Mono, RubyMotion, etc).<p>This wasn&#x27;t always the case, but IIRC the current review rules only forbid having a runtime scripting language that isn&#x27;t JS (since Apple can happily sandbox JS), but anecdotally even that isn&#x27;t a problem these days (e.g. plenty of games use Lua for in-game scripting).
