Question

I have understood the basic concepts of core data and how to create schemas or data model in xcode. However I am struggling to create database and import it xcode.

I don’t have any experience with creating databases before.

Can somebody guide me here.

Thanks in advance!

Answer 1

If your application is document based, the database is the document. You create it in code when you create the document.

If it’s not document based and will use just one single database, then you generally create it in code the first time the application is run (or, more likely, whenever the application is started and it cannot find an already existing database).

In either case if the database can start empty, that’s all you need. If an empty database would be invalid and you do need some minimal data when you initialize it, you will have to populate it upon creation.

Depending on how much data your minimal database needs to have you can either hardcode the initialization or use a static resource (that is, a file) in your application bundle containing the initialization data in some form that you know how to read and use that to populate the database.
