42,016 Pointsok it looks like you need to capitalize Shape. Class names usually start with a capital letter and if you followed along in the video your class is most likely named Shape. so try
Shape *shape = [[Shape alloc] init];
Stone Preston
42,016 Pointsit means your shape class doesnt have a method called alloc in its interface. Is this for a treehouse challenge or video? if so please provide a link
Stone Preston
42,016 Pointscan you please post the code that you are using in your main method

42,016 Pointsdid you import your Shape.h in main.m? does your shape class inherit from NSObject?
