This copy of libswiftCore.dylib requires an OS version prior to 12.2.0

Got it fixed in our ObjectiveC-only project by adding empty Swift file. Don't remove it, just keep it there forever!
Make sure /usr/lib/swift
is the first argument for runtime search
paths for linker if iOS >= 12.2, it should load platform libraries.
