This error goes away when you go into Building Settings >> Signing >> Other Code Signing Flags and set it to "--deep"

Actually re-opening this.
Even though we have a signed fmodex.dylib now which stops the error most users were having any other project with unsigned dylibs will get code signing errors ( even on 10.14 ). Adding --deep as above will fix signing for all scenarios.
Will submit a PR with a fix
I just updated to OSX 10.1. Thank you, it solves the problem.
