Unity 3.5 Xcode crash, compiler error iOS 5.01

Hi guys, I've $$anonymous$$t another brick wall with unity, it was working fine, and now its throwing up a compiler error in XCODE, I've tried 4.3 and reverted to 4.2 un-installed unity & re-installed, re-deployed all sorts and to no avail. I'm on a tight time-limit to get t$$anonymous$$s sorted and I've not found a way to see any change!

I'm getting t$$anonymous$$s error.

Unfortunantely I've only got experience with unity & not the iOS dev tools, so t$$anonymous$$s is causing major trauma! haha,

Anyway thanks in advance for all the help!
