The exercise:
Given that you label the method developed in exercise 1 the designated initializer for the Rectangle class, and based on the Square and Rectangle class definitions from Chapter 8, add an initializer method to the Square class according to the following declaration:
-(Square *) initWithSide: (int) side;


We have covered type "id" on page 194, and designated initializers on page 206. Would it be more correct to declare "id" as the return value data type than (Square *)? OR have we not reached this point yet?

After the last problem in chapter 9, I am assuming that if you know the type I object that you are working with , then you would use that object (Square *) Instead of (id).
