ViewController "file"?

So I'm thrown off a little bit when he uses the term ViewController "file" (1:28 in the video). Does he mean the ViewController file is an instance of ViewController class? which in turn is a subclass to UIViewController? Just trying to connect that word "file" with what I have learnt so far in Swift.

ViewController it is a subclass of UIViewController, when you create a new project you have a default ViewController, but if you notice in your project navigator you will see it is a .swift file, if you clic new file, IOS Source, cocoa Touch class, you can add a new file with the class ViewController, subclass = IUViewController. This would create a ViewController2 in your project. View Controller is a Swift file, subclass = UIViewController.

Ahhh That makes sense! The class and super-class where automatically assigned to the ViewController file created with the project. Thanks a lot!!
