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

If you are facing an error like that on new MacOS version.

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

It means that you need to install XCode command line, open a Terminal and run this command:

$ xcode-select --install
