Whatever sort of object FileName is, the compiler can’t find a method named ‘-failWithException’ in that class. The solution is to go implement that method on that class, or to make sure the compiler can find the header file where it already is implemented.
By the way, it’s a warning instead of an error because, unlike for instance Java, Objective-C allows you to manipulate classes at runtime. So while you PROBABLY have a problem there, you don’t DEFINITELY have a problem, so the IDE gives you a yellow warning rather than a red error. But in your case, this is almost certainly something you need to fix.
