Failed Unity game built on Xcode

Hi guys,

I tried to distribute a game on iOS Appstore. The game worked flawlessly on Unity and Android devices, however when built on Xcode, it gave an error like this:

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 254

Since I’ve only worked with Unity, not Xcode, I have no clue how to fix this problem. Can anybody help me ? Thanks a lot !

I have the same proble. Is there any fix? xcode 5.1, unity 4.3.4, mac os 10.8.4

Any solutions?
