What could > cause the array to have a -1 count? The return type of -[NSArray count] is NSUInteger so no it is not negative one. But you are logging it with %d which is for signed integers. So, certain unsigned values would log as negative one, unsigned max comes to mind as its twos complement should be negative one when interpreted as signed.
