> The bundle isn't normally writeable by the app itself. It's generally good security practice to not have your app capable of rewriting what itself can do, and iOS is the same way. You can't write into your app bundle, so anything at all that you want to persist needs to go somewhere else (typically in "Application Support").

I don't buy this. If you are writing "anything at all" into Application Support, this is no different than writing to the bundle. An executable binary written into Application Support is just as effectively the same thing as an executable binary written into the bundle itself. I don't see a difference between a program rewriting its own code vs. writing an executable into another location.

There's no added security and no added user value to writing into Application Support vs. the App Bundle itself.

Not arguing with you, I appreciate you explaining the current state and conventions. Thanks for the discussion.
