I initially started writing a blog post that discussed various alternatives to Key-Value-Observing (KVO) in Swift, however, I found myself writing more about the task of implementing events in Swift. So, I’ve decided to split the problem in two, in this post I’ll cover events, and I’ll follow-up with the KVO post later on.

I’m certainly not the first to blog about this topic, Mike Ash published a great article on Swift implementation of NSNotification just last week. However, in this post I’d like to approach the problem in a slightly different way, starting with a naïve implementation.

Let’s start at the beginning …

WHAT ARE EVENTS?
Cocoa has a number of techniques that allow classes to collaborate in a loosed-coupled fashion via some form of notification, including target-action, the delegate pattern, NSNotification and KVO. These are all forms of the classic Observer Pattern, yet all are different implementations, and each have their own failings.
