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

In my case it was about having a file named Location. after some digging I find out that it was about having two file with the same name (weird). Cause I don't, however, it's been solved by removing the file and adding another file with a different name.

filenames are used to distinguish private declarations with the same name
