ios 7 and xcode5

Has anyone used xcode5 and built their apps on ios7 yet? I am afraid to upgrade to then run into the issue of having my app not work on the device. Please advise


Yes, I have had a day of updates today. Updated Mac OSX to Mountain Lion + Xcode 5 + iOS7

Built successfully with Unity 4.2.1, no problems.

With the new update to Unity and Mac OSX Mavericks build & run now works again.
