Update: My Core Data model is now mirrored in the CloudKit schema. It started working once I removed Configurations from the model and stuck with the default. Remains to be seen whether records will save both locally and to CloudKit but at least schema is showing up now.
As a side note, I still receive many of the same console errors as before regarding failed requests and "no auth token for asset"
