is it prohibited using of JIT(just-in-time) compiled code in iOS app for AppStore?

Question

I heard that JIT compiled code is not allowed in iOS AppStore because placing executable code in heap is prohibited. It that right? Or just a rumor?

Answer 1

1. Installable code isn't allowed ("or" is the key word in 3.3.2). Everything (except Javascript) has to be statically linked.

2. JIT compiling into Javascript source code text appears to be allowed. (Not a joke, there is a commercial compiler that does this.) Compiling into bytecode for execution by an interpreter written Javascript and running in a UIWebView may confuse the reviewers enough to possibly reject an app doing that.

3. The iOS security sandbox will likely kill any app that tries to jump into any dynamically generated data.
