I have the same problem and am using Xcode 5.1.1 and unity 4.5.0 on the latest Mac OS X.
In my case my Assets/Editor folder contains a “XUPorter-master” folder, which contains a “PBX Editor” folder, which contains a “PBXParser.cs” file, which appears to contain the bug.
I can build & run on Mac just fine, but here is the error/stack trace from my Unity console window when trying to build for iOS. Below that is the code for “PBXParser.cs”.
Is this something built into Unity or something that came with an add-on?
