....but then goes on to talk about various predicates (like "where
salary is over 10000").
I simply want "all employees".
I've looked through the documentation and found
"countForFetchRequest: error:"
but that still leads the question of what kind of request asks for
"all objects of a certain type".
What do you think happens if you don't set a predicate?
Did you try it?
