iOS prohibits JIT for example.

  More specifically, apps submitted to the App Store may not utilize JIT.

    Is there any specific reason for this?

      Allegedly security. Apple only trusts Apple.

      Executing instructions dynamically from memory (JIT does this) exposes potential security issues. A good example is the famous Specter vulnerability. Specter itself is not JIT-specific but it is known to very hard to reproduce that the only current viable target environment is JIT. So JavaScript was affected by Specter.
