Answer 1

The tables error occurs because of the difference in the structures or schema of the two tables.

Please go through this previous SO question to get a better idea Pre-load existing data into a Core Data-based iPhone app?

Answer 2

A fairly simple way to do this is to save your data in a plist file, organized as an array of dictionaries - then at launch check if the Core Data database has any records, and if not read in the plist file and populate the database.

You'll need a plist file for every table, so this is most viable for simple databases.
