Question

i am working on an application that displays read-only data i am shipping.
it is more of a book.

It is easy with SQLite but i am not satisfied with the performance and trying to use Core Data.

The issue is with pre-filling Core Data is that it is a hard process.

My question is:
Is it possible to build an assistant iphone application (for me to use) which uses the same data model for pre-filling.
and then take the populated .xcdatamodel file and use it in my original application?

I hope this makes sense 🙂

I believe what you’re asking is whether you can create a CoreData database upfront and copy it to the iPhone. Is that correct?

This article will help. Here’s a quote:

I thus suggest the following five-step process:

1. Create your data in a comma-separated file, typically placing each row of data (an entity) in a row of the file and separating different columns (its attributes) by commas.
2. Write a standalone program and copy in your .xcdatamodel file from your main project.
3. Write code in your new program that parses your comma-separated file and inserts the information into a Core Data persistent store that should be identical to the persistent store in your main project.
4. Run the program in the Simulator
5. Copy your data from the Simulator’s documents directory into your actual project’s bundle.
