Summary:
When generating an NSManagedObject subclass from a Core Data Entity having fetched properties in XCode's Core Data Data Model Editor, fetched properties are not included in the output representation.

Steps to Reproduce:
1. Add a Core Data Model to an XCode project.
2. Add an Entity to the model.
3. Enter a fetched property, with predicate, to the Entity.
4. From the Editor menu, select "Create NSManagedObject Subclass..."
5. Generate the class. Output will look something like this:

Header:
@interface Entity : NSManagedObject


@end

Implementation:

@implementation Entity


@end

Expected Results:

Header:
@interface Entity : NSManagedObject

@property (nonatomic, retain) NSArray *someFetchedProperty;

@end

Implementation:

@implementation Entity

@dynamic someFetchedProperty;

@end

Actual Results:

Generated class:

@interface Entity : NSManagedObject


@end

Implementation:

@implementation Entity


@end

Regression:

This has been the case not only for XCode 5, but all previous versions of XCode 4 that I can recall. Definitely in 4.6.3.

Notes:
This is particularly applicable to developers who are attempting to separate user data from application data in core data by maintaining stores in two locations using fetched properties.
