Adding is via a button going to an Employee array controller's -add.
In the interface there are 2 array controllers (1 for Departments, 1
for Employees). The Employees controller is set to use the selection
in the Departments controller (i.e. showing the subset belonging to
the selected dept).
Adding and deleting Departments and Employees is fine (everything gets
hooked up / added / deleted properly), and if I look in the XML Core
Data store, all is well. It's just my custom accessors (the 4
mentioned below) don't get used, whereas -setEmployees does.
Do you reckon it's because the adding is happening from the Employee
side of things rather than the Department side of things? Shouldn't
both sides have their accessor methods called (thanks to the inverse
relationship)?
I can't believe it's relevant, but the Department's 'employees'
relationship is mandatory, as is the inverse relationship.
Weird isn't it :)

Yep I implemented all 4, as per the Design -> Data Model -> Copy to

- (void)addEmployeesObject:(Employee *)value;

- (void)addEmployees:(NSSet *)value;
- (void)removeEmployees:(NSSet *)value;
However if I implement -setEmployees as per Jerry's e-mail (and
seemingly contravening the advice in the Core Data Programming
Guide), then it works like a charm :-/
There's something else going here, though it isn't clear what. One
thing you haven't said is *how* you're adding employees. Could you
show the code that does this?
