        Currently I'm developing plug-in software that must work in both legacy 32-bit as well as 64-bit applications. From Xcode 10, support for building 32-bit binaries was dropped, so, I continue to use Xcode 9 to build and sign 32-bit/64-bit fat binaries, and these get packaged into a .dmg file, and the altool and stapler utilities from Xcode 10 are used to notarise the package for distribution.


        I recently upgraded to macOS 10.15 beta, but now Xcode 9 won't run.


        The following crash occurs:

        Is there any way to build 32-bit/64-bit fat binaries on macOS 10.15? If not, will this mean I need to downgrade to macOS 10.14?
