Icon dimentions (0 x 0) don't meet the size requirements

Since the last version of Unity 3.5.6f4 , when i want to submit my app with xcode4.2 I get this automatic error :

“icon dimentions (0 x 0) don’t meet the size requirements” for both icons 57 and 72

Any idea ?

by chance did you try this ?

Well I found the solution :

Update the Mac OS X Montain Lion
Install Xcode 4.5

Then it worked.

If you want to keep your old xcode, and OSX, don’t install the Unity 3.5.6f4
