You can do this without leaving Xcode at 13 all (see end of answer for XCode 4 instructions):

Open your data model so it's visible in the editor pane
Single click Classes folder in Group & Pane pane
Now single click anywhere in the diagram pane.
Press ⌘N to bring up this dialog:

alt text

Finish the wizard to genereate code for one or more classes. Note: you select the classes for which to generate on a later step in the wizard - not shown here.

I 12 picked this up on page 143 of More iPhone 3 Development

Update 12/6/2010:

Alternatively, you 11 can just select one or more of the entities 10 in the entity list, as shown below: alt text

And 9 then press ⌘N to bring up the New file dialog 8 shown above. If you accept the default location 7 using this alternative, the generated classes 6 will be put under your .xcdatamodel. Drag 5 them manually to classes (Ref: Stanford, Developing Apps for iOS: ep. 12. Core Data and Table Views).

Update 3/26/2011 (Xcode 4):

For XCode 4 4, simply bring up the New file dialog (⌘N) and 3 select NSManagedObject subclass from Core 2 Data. The wizard will ask you for which 1 enities it should create classes.
