James,
I have a feeling that KVC will wrap your double values
("calculatedRewardScore") into the Double object. So what you actually
get is an Object[] (actually Double[]) instead of double[].
Is Double[] good enough for what you need or do you still need double[] ?
regards
Peter

That gives me a compiler error. I tried that too. Searched around ...
I guess I just have to loop through.

Is there a way to use KVC to:
1) Given an array of EOs
2) Get an array of attribute A1 which is a double.
Not directly.
I was hoping to do:
double[] y =
(double[])projects.valueForKeyPath("calculatedRewardScore");
but this throws an exception.
What am I doing wrong?
valueForKey (and valueForKeyPath) on an NSArray return an NSArray
(unless using an aggregate function like @sum, in which case they
return a Double IIRC). What you want is (warning, untested code):
double[] y =
(double[])((NSArray)projects.valueForKeyPath("calculatedRewardScore")).objects();
