Build fails with “Command failed with a nonzero exit code”

Question

When I try to build my app with Xcode, an error interrupts the build process:

Command CompileStoryboard failed with a nonzero exit code

Answer 1

I have faced similar problem. I have done

• clean project - didn't work
• Remove Derived Data Folder - didn't work
• Change build system to Legacy Build Settings - didn't work
• Restart XCode - didn't work
• Comment some of my code, a typedef NS_ENUM in .h file and enums related works. Build the system and build success shown. Next un-comment the code and build again - Magically works
