There should be more than just that one line. C requires that functions be declared before they are used; if they are not, it assumes they take any number of parameters and return an int. At the points at which you call colorName, the compiler hasn't seen a declaration for colorName yet, but can infer that it is a function from the way you're using it. So it assumes it's "int colorName()" and continues on its merry way. Then when it sees your definition of colorName later on, it complains because the definition "NSString *colorName(ShapeColor)" does not match the assumed "int colorName()".
You have two options: 1. Provide a prototype of colorName somewhere before it is used. Typically this is done in a header (.h) file which is #imported by the source (.m) file. 2. Move the definition of colorName before it is used. I also suggest you consult your favorite C language book for more.
