When you create it without initializing it, its size automatically defaults to 0, until you add items to it. Therefore, you're output should be
NSMutableArray *elements = [NSMutableArray array];

3,118 PointsThanks Rashii. I figured it out. Your answer is probably write too. But this worked for me:
NSMutableArray *elements = [NSMutableArray arrayWithCapacity: 0];
