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

That is right. You can read in the iOS standard agreement, which you need to accept when setting up your developer enrollment:

3.3.2 An Application may not download or install executable code. Interpreted code may only be used in an Application if all scripts, code and interpreters are packaged in the Application and not downloaded. The only exception to the foregoing is scripts and code downloaded and run by Apple's built-in WebKit framework.
