Thanks for the addt'l info. Note that it's only a stub method, to be replaced with one provided by a 3rd party. I wanted to quiet the 'noreturn' warning mostly out of curiosity, since I had never seen

Are you sure `noreturn` is appropriate there? I mean, the name "providerCV06" kind of sounds like it actually does something. A `noreturn` function literally never returns, i.e. it either throws an

You can set them to be an entry within a plist. I did that for the build environment so that we can determine if an app is built for debug, test or release. I’ll look for a sample and get back to

Xcode 11.3.1 How can I read Xcode build symbols (e.g., $(MARKETING_VERSION)) from within my macOS app? -Carl
