I am trying to generate classes for my .xcdatamodel entities, but am not given

  • 0

I am trying to generate classes for my .xcdatamodel entities, but am not given the Manage Object Class option when I click on an entity and select File>New File. I’ve looked under both the iPhone and Mac OS X catagories, but it is not listed anywhere.

Here are the steps I am taking,

I create a new project being sure to check the “Use Core Data” checkbox. Once the project is created, I open .xcdatamodel, create an entity, and add a few attributes. Next, I click on the entity and choose File>New File, but all I see are only Objective-C, Objective-c test case class, and UIVewController subclass.

Am I missing a step?

Thanks in advance

    Take a look at the Core Data Tutorial for iPhone OS and look at this section: Custom Managed Object Subclass. If you still aren’t seeing the Core Data related items for the iPhone OS check the version of the SDK you are targeting. I believe Core Data has only been available since SDK 3.
