Hi, thanks for the reply! I did step through the code, and it seems like the call of loadPersistentStores does generate an error, it's just telling me Core Data is failing to load. I don't have a CloudKit container called "TaskDataModel", but all the tutorials I found just changed NSPersistentContainer to NSPersistentCloudKitContainer with no issues, so I'm not exactly sure what is going on. Thanks for the help!
