Switch to use Core Data during development?

Question

Hi,

I decided to switch to use Core Data to save all the data in my navigation application. What are the steps necessary to make Core Data available in my application?

I don't want to start a new project with the check box 'Use Core Data for my application' and copy all the existing codes to the new project.

Anybody has any guides or tutorial?

Thanks,

Also here is the link to Apple's Core Data Tutorial As a side note you don't have to use Core Data, you can use SQL Lite, I have found it to be a little easier starting out if you are all ready familiar with the basics of SQL.

You need a CoreData stack consisting of:

1. NSPersistentStoreCoordinator

2. NSManagedObjectModel

3. NSManagedObjectContext

The easiest is probably to create a dummy project with CoreData enabled and then to copy the stack from the App-Delegate to your project. Don't forget to link in the CoreData Framework.
