# After creating the new MovieViewController class, I get the following error when running the app: [Storyboard] Unknown class _TtC15rotten_tomatoes14ViewController in Interface Builder file. Do I need to connect this MovieViewController to the main storyboard somehow? ## Solution: Way 1: deleted the original ViewController, which is probably the root of the issue. But there is no ViewController.swift in the ‘Create a Network Request’ video from the module Way 2: Rather than creating a new ViewController, I refactored the class name of the original ViewController.
