Might start with updating your Xcode package. You are running an early beta release. There are newer betas out, or better yet install 4.6. To be fair, I really haven't messed with Xcode 5 yet so this may or may not help. Tim

You might have 2 copies of a framework. I would try to start from the beginning. Everytime I get that duplicate symbol error it is usually because of duplicate frameworks.

I never thought of that. Thanks, ill give it a burn through 4.6. I kept both around for this sort of issue, and didn't even think of it. Thanks Jeremy

Let me know how it works out.

deleted duplicate

Thanks fred, ill check that out

3 duplicates, still failed with the same error. No luck.

Start all over with a fresh project

Yeah i think so. Ah well iv'e had a break, now will have another go.
