Taking example from Apple docs using predicates with Key-Paths

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY employees.firstName like 'Matthew'"];

Now, assume the employees has a bool field "isGood". The question: how do I select just those entities, having ALL of employees isGood==TRUE?

I tried but failed with following predicates:

"!(ANY employees.isGood != TRUE)"
"(ALL employees.isGood == TRUE)" // Would be perfect, but throws an exception..
