in short: you cant :)
longer:
you need to keep using sqlite if you wanna keep the db. You can't easily'migrate' a DB from sqlite to cordata. coredata does USE sqlite - true - but it does so in a 'private/proprietary' format that isn't documented and can change over time.
==> stick with sqlite
IF you need to switch, open the old db on the device and write a class to read from sqlite and import to CD.
=> you still need to write a swift sqlite 'reader' class and a core data importer

Core Data uses an ManagedObject model and will use a slightly mangled naming convention in its SQLite-based backing store. You may not be able to use your old SQLite database due to table names being different.
What you may want to do is migrate your old data from your old SQLite db file to your new Core Data SQlite backing data store.
