What is the best way to bind Core Data entities to enum values so that I am able to assign a type property to the entity? In other words, I have an entity called Item with an itemType property that I want to be bound to an enum, what is the best way of going about this.

You can do this way, way simpler:

typedef enum Types_e : int16_t {
    TypeA = 0,
    TypeB = 1,
} Types_t;

@property (nonatomic) Types_t itemType;

And in your model, set itemType to be a 16 bit number. All done. No additional code needed. Just put in your usual

@dynamic itemType;

If you're using Xcode to create your NSManagedObject subclass, make sure that the "use scalar properties for primitive data types" setting is checked.
