There is a more permanent fix for this. Fixing the attributes in the DerivedData works, but the problem keeps coming back. What you need to do is go to the directory shown when you get the 'resource fork, Finder information, or similar detritus not allowed', the one that contains the .App file. Then execute...

xattr -lr MyAppName.App

You can then see the resource files that have the attributes that need removing. Don't remove them from the .App file though, find the original files in your project and open the directory that contains them and execute...

xattr -rc .

This then fixes the ORIGINAL files. Rebuild should then function ok. It should also then rebuild properly for archive too.
