I have two Copy Files steps in my project Build operation. One copies a helper that the previous steps builds (which is succeeding) into the App Parent Folder and the second copies a fixed tarball and set of icns files into Resources.
I get no errors during the build, and the actual IDE scripts are running, but the copy steps are either failing quietly or not running?
Here is a Mac bug report for Universal: 65352 - Build Copy Files don’t work on Universal architecture 65342 - copy files step in macOS Universal Binary console app fails to copy anything
