Using a custom class final quiz.

The question is asking me to: "Create an instance of the Song class with the convenience constructor songWithSinger:(NSString *)s and singer named "James Brown".

What I've been using is:

Song *popSong = [Song songWithSinger:@"James Brown"];

Can't find what I'm doing wrong.

your answer indeed is correct but you have to make sure that there are no spaces after the colon (a Quiz checker thing) and it should work. You might also want to have a look at here

Thanks for the help Holger. This type of issue keeps holding me up during the course, very frustrating.
