Suppose I have a Core Data model object MyObject with property
myProp
defined in the model editor's schema.
Can I use the simple accessors like this:
[myObj myProp]
[myObj setMyProp]
or am I forced to use the rather clunky valueForKey/
setVakyeForKey messages?

Managed objects automatically fake accessors for entities.
No, they don't fake accessors for entities, they dynamically
generates accessor methods for managed object classes.
I call this fake.
"Fake" is not terminology that is used in this context, and it's at
best misleading.
The system dynamically generates accessor methods, that's it.
You can subclass NSManagedObject and add properties using
@property and @dynamic, which means, that the accessors will be
generated dynamically at run-time. (Without @dynamic you will get
a compiler warning: incomplete implementation blablabla)
There is no need to create a subclass,
"You *can* subclass NSManagedObject …"
you can use a category instead.
There is no need to create a category. You can use a subclass instead.
It's not clear what your point is.
There is no need to create a custom class if all you're doing is
declaring accessor methods. Your reply did not state that.
There is documentation about @property and Core-Data esp. in
relation to retain/copy/assign. (The quintessence: Use retain!)
You may also consider 'copy' if appropriate
"There is documentation about @property and Core-Data esp. in

You gave no pointer to the actual documentation.
It is important to also consider the use of 'copy' since it is
important in some cases.
