I'm just confused as to why accessing the count method of NSArray would
crash when I just initalised it. Any ideas?
First off, a terminology nit: You're not "accessing the count method
of NSArray," you're sending an NSArray the -count message. The
programmer sends messages, the runtime invokes methods.
Secondly, you're using the %@ construct and passing it an integer
argument. %@ means "interpret the corresponding argument as an object,
and print the result of sending it the -description message." Since
the result of sending -count to an NSArray is an int, which isn't an
object, that's why you're seeing a crash. Just use %d instead.
