Code Challenge: Adding the Edit Friends Screen

So here is the problem. The first task asks to set the "query" variable. But the compiler will accept it even if the PFQuery is not declare. (PFQuery queryWithClassName:@"Apps"; will work but it needs to be: PFQuery *query = [PFQuery queryWithClassName:@"Apps"]; ) The fact that the compiler accepts it makes it impossible to do the second task wich involves calling the "query" variable.

It would be impossible to do that in a real app too, right? :smile:

Hi Ben, I am on the second question and have entered: [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (error) { NSLog(@"Error: %@ %@", error, [error userInfo]); } else {

    }
}];

I am extremely confused on why it won't work. My error message says "Bummer! Compilation Error! Make sure you have the correct syntax and are calling the method and passing the block like in the video."

NVM Ben I just figured out that I have to add PFQuery *query = part during step two. Thanks anyway!
