Which version of Xcode does Unity 3.5.5f3 support?

I currently have Xcode 4.4.1 and just BARELY allows me to build successfully and run - only when I build from unity with iOS5.1 and the same from Xcode 5.1. Which versions are you iOS devs using? And is there any insight on when iOS6 builds will be supported? I’m itching to update my iPod touch to iOS6 but I still need it for testing purposes (it’s currently 5.1)

My configuration never changes, regardless my Unity or Xcode versions:

SDK Version: iOS latest
Target iOS version: 3.1.3

With a target less than 3.1.3 you can’t target iPad devices, so with this configuration you can reach most devices. (Every iPad and every iPhone with at least 3.1.3).

I hope it helps.
