Using Xcode 4.5.1. Our project has been building fine for the last three months, but suddenly, when I try to build, it says “Build failed”, but does not show any errors on the triangle exclamation mark tab, nor does it give a reason when it pops up build failed.
We have not changed the bundle identifier, or any other project properties. I tried a clean, then build, but no luck.
What may be causing the problem?
Similar to this question, but none of the solutions apply.
