I get the following error in the debugger:

I know this is some stupid rookie mistake, that I am missing some
fundamental understanding here, but could someone be so kind as to
point out the flaw of sending an int directly in such a manner?
Scalar data types like int, char, and float are not objects.
NSMutableArray and its related collection classes contain objects, so
that's the only kind of argument you should pass to -addObject: etc.
One way to create an array of integers is to use the wrapper class
NSNumber.
