URL title: Observers as an alternative to delegates – – Some chatter, babble and prattle about things I find interesting.
URL description: 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.
