Xcode: Build Failed, but no error messages
build, xcode
Solution
Figured it out. On the tab with three lines in a speech bubble, it shows a build log. I guess my storyboard file had become corrupt during the last git pull.
For Xcode 12+
Problem
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.
