iOS Download code when app is running

Question

I am aiming at downloading code (library / framework / bundle) when the app is running. This is like download specific modules based on user's ACL.
I have gone through creating static library and framework which seems like we need them when code signing app.
But I need the code to be downloaded when user is using the app and run that code.
Pls provide some samples

Apple does not allow apps that download and execute code. – Tressatressia

@Tressatressia Thanks. Any references for this from apple website? – Shouse

Yes, it is in the AppStore Review Guidelines. 2.8 Apps that install or launch other executable code will be rejected and 2.7 Apps that download code in any way or form will be rejected – Tressatressia
