Description of the issue:
I installed Unity and switched to the iOS build settings. When I load the ARDK package, I get these error messages:
#Niantic.ARDK.Internals.StartupSystems#: Could not load an ArdkAuthConfig, please add one in a Resources/ARDK/ directory. For more information, visit the niantic.dev/docs/authentication.html site.

I tried following the instructions from the first error (ArdkAuthConfig), but then I got a different error and had to boot in safe mode. How can I fix these errors? 
Thank you,
Erik
