{
    ... 
    [operation setCompletionBlockWithSu         


        

Answer 1

It is already an NSArray, something you can verify by calling:

BOOL isKindOfArray = [responseObject isKindOfClass:[NSArray class]];

NSArray is implemented as a class cluster and one of the private subclasses that it might return is __NSCFArray.

The point of a class cluster is that the framework can provide different implementations under the hood that you don't really have to care about. As far as you should be concerned, it's an NSArray.
