Swift 7.3.1 Change to ViewController and AppDelegate?

I am working with Swift Version 7.3.1 and instead of the ViewController.swift and AppDelegate.swift files on Pasan's screen, I am seeing ViewController.h, ViewController.m, AppDelegate.h, and AppDelegate.m.

Will these changes be significant? How do I know which files to open to follow along? Does anyone know of a good resource with explanations of these changes?

Alternatively, did I do something wrong in the setup process that would have caused this difference?

Hey Sonia, I'm assuming you mean Xcode 7.3.1 (Swift is only at v.2.2).

By looking at your question, I think you did err in the setup for the project Pasan is going to work on.

"ViewController.h, ViewController.m, AppDelegate.h, and AppDelegate.m" are Objective-C files and "ViewController.swift and AppDelegate.swift" are Swift files. So when you where setting up the project, you had Objective-C selected as the language (instead of Swift).

If you delete the current project and start over, it is an easy fix. Have a look at Creating a New Project at ~5:15 time stamp.

Keep Coding! :)
