Xcodebuild not display warnings and errors?

Question

I run xcodebuild, but the warnings and errors of the source code are not displayed on the command line. He just says that CompileC failed. How to get xcodebuild to display warnings and errors at source level?

Answer 1

The problem often lies in the fact that the error occurred above the stack, but then the message is completely absent at the time when Xcode displays an error message. Try to run:

xcodebuild | Grep error

and he often gives more helpful tips than before.
