Distribute iOS static Library

I have compi开发者_运维知识库led 2 static libs of same code-base, one for simulator and one for device. I would like to know, whether should i submitted both libs to Apple.

Or can I create a universal static lib, which can run on both Simulator as well on Device. Is it recommended by Apple to submit only universal library ? How can I produce that ?

Apples don't care about code for iOS simulator and thats shy when you build application for submit, binary for i386 architecture won't be compiled by default and that's correct behavior. Just build for device and submit it, everything will be OK.
