Here's a web page with an interesting take: https://www.mikeash.com/pyblog/friday-qa-2015-07-17-when-to-use-swift-structs-and-classes.html

There's a section in the Apple documentation on when to use which: https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/ClassesAndStructures.html

You will need to scroll down to the Choosing Between Classes and Structures section.

A general answer

Use structs when you need a value type, and use classes when you need a reference type. and use classes if you think you'll want to use inheritance.
