It sounds like this could be an issue with Xcode 11, so it is likely that we won’t see the error if we build our projects with Xcode 11. Unfortunately, Unity Cloud Builder is still on 10, so that will be broken for the time being.
Apologies – I just realized UCB doesn’t output that information for some odd reason. Here’s the output directly from Xcode:
Undefined symbols for architecture armv7:
