Why do we need separate “.swift” files for each class?

Question

Wondering if you might be able to answer a very basic beginner question for me. I’m working through the Cocoa + Swift tutorial on Lynda and I’m a little confused about class

Answer 1

I also vote +1 to your question, and for the upper answers.

As a newbie I really agree it is difficult to get the classes and inheritance concepts.

But believe it is much better to handle code in separate documents, perhaps using MVC concept, rather than having this code in a single massive document.

My own experience, it clears out the clouds of your code.
