With what version of Xcode?

MacPorts base doesn't allow universal builds when only the 10.14 SDK or later are available (i.e. with Xcode 10 or later) since the SDKs don't have the i386 parts anymore.

https://github.com/macports/macports-base/blob/master/src/port1.0/portconfigure.tcl#L392

It is known that the error message shown is not worded very well to explain this. I can't find the ticket right now.
