I got this error message while running my app from within Xcode and the Archived exported app do NOT execute under macOS 10.14
[default] Unable to load Info.
I have the same problem with my project - everything builds fine, but nothing show up except that error:
Unable to load Info.plist exceptions (eGPUOverrides)
It IS Mojave bug. Apple trying to fix this issue in the next versions of Xcode. For now, I recommend to just downgrade the IDE for 9.4.1 version and waiting for resolve. It was the only option worked for me.
