| | This has come up several times on the forums, but I've never written it up in a standard place, so here it is: **There are only three ways to get run-time polymorphism in Swift.** Well, three and a half.

| | Recently I started studying Ray Wenderlich's tutorial book RxSwift. Early on, the book suggests using Rx as an alternative to delegates and their associated protocols. I though, great, but, for the task at hand, that's a rather heavy handed solution. (Yes, I know it is just an example designed to teach me the basics.) So I tried to imagine how I could achieve something similar to the functionality they built for their initial examples, without the overhead of importing a big library like RxSwift.
