One of my favourite blog topics is poking fun at Xcode and all of the bizzare problems I encounter with it. The most recent one was a compiler error that looked like this:

fatal error: file '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform
/Developer/SDKs/iPhoneSimulator6.0.sdk/usr/include/Availability.h' has been modified since the precompiled header was built

Strange, right? Fortunately, it was an easy fix – all I had to do was a Clean. After that, it compiled correctly.

What boggles my mind is that Xcode knew exactly what was wrong, but wasn’t smart enough to fix the problem itself. Maybe I am being unrealistic here, but it seems to me that a file included in the precompiled header has changed, the correct behavior would be to, you know, recompile the precompiled header?

Then again, it’s Xcode. So I guess not.
