I found https://developer.apple.com/documentation/financekitui/addordertowalletbutton and https://developer.apple.com/documentation/financekit, but neither of them has any documentation whatsoever—it’s like they’re not meant to be discovered. Could you confirm I’m looking in the right place?

You’re right in that LSApplicationWorkspace is a pretty powerful class. Among other things, it can launch apps by bundle IDs, which I initially wanted to use for opening Settings’s main screen (the UIApplication.openSettingsURLString constant points to an app’s settings, which wan’t quite suitable for my goal).
Sure, I tested the production config, and the conditional compilation with #if DEBUG behaved just as expected. Nevertheless, analyzing the archived app with strings did produce LSApplicationWorkspace among other strings.
I suspect this may have to do with Strip Debug Symbols During Copy (COPY_PHASE_STRIP) and/or Generate Debug Symbols (GCC_GENERATE_DEBUGGING_SYMBOLS) build settings which default to NO and YES, respectively, for all configurations. Haven’t tested it yet, though.
