Rez failed with a nonzero exit code


So I recently started a new project after updating xcode. By default the au component wont build, due to this error: Rez failed with a nonzero exit code.

I’ve seen some different solutions on this on the fora but it seems like none of them apply to my project or actually fix the issue. I have already added the Extras/CoreAudio, but this didn’t help. Do I Maybe need to include it somewhere again?

Anyone have experience with this? Thanks!

I have this question too? How can a question over a year ago still not be answered, at least by the JUCE developers since it’s happening as a direct consequence of using ProJucer
