问题
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
