Comment (by ryandesign):

 In Xcode 10, Apple [https://en.wikipedia.org/wiki/Deprecation#Software
 deprecated] the i386 architecture, meaning it still works but Apple
 thereby notifies you that it will be removed in the future. Building for
 i386 was removed in macOS 10.14 and running i386 code was removed in macOS
 10.15.

 If you wish to build i386 software (including building universal for
 x86_64 and i386) on 10.13, I recommend sticking with Xcode 9. That is what
 I do on my 10.13 system and what we do on the 10.13 buildbot worker.

 That doesn't mean we shouldn't fix the problem in this ticket, we just
 haven't yet.
