What a great tribute you have written. When I first found about swizzling through a seasoned iOS dev I was blown away. The swizzling capability in obj-c basically helped create my first startup, InstaOps, a long time back which allowed no code change to instrument an app to capture logs and network performance metrics.

I second all of these comments. I was on the same team with him (Hi Prabhat, this is Paul D.) and concur that swizzling is a very powerful mechanism. It's definitely a good thing to know about if you're working with Objective-C.
