I dont understand why this line of code dose not work. bookTitle = bookTitle.uppercaseString;

Please explain why this is not a proper solution or is there a problem with the test. This should work for capitalizing all the letters in the string.

arrays.mm 
    NSArray *booksArray = @[@"Hamlet",@"King Lear", @"Othello", @"Macbeth"];
    NSString *bookTtitle = [booksArray objectAtIndex:2];
    bookTtitle = (NSString *)bookTtitle.uppercaseString;
