Cocoa Touch is a UI Framework used for building software programs to run on iOS. You can think of it as a swift file that comes "ready made" with a few things for you to use. For example, the UITableViewController Cocoa Touch object comes pre-filled with methods necessary to make the table view work. UICollectionViewController is another example.

A swift file is just that - an empty swift file. There is nothing pre-populated inside of it. Empty swift files are typically used for custom classes, structs, enums, etc. Once you start building more applications the difference will become apparent.
