Argh. macOS 10.14.6 is what I tested it on in the first place.

Out of curiosity, what Xcode version? Not that I was expecting this to
happen; the Stack Overflow answer I sourced this from was supposed to be
compatible going back many macOS versions.

Best revert the change. I don't think I have a way of tracking down
what's causing this error.

Cheers,
Andrew
