Lately, I've seen a lot of people claiming that the Objective-C runtime is something worth avoiding. I don't find this to be true. It is highly optimized, with hand written assembly, and it is very fast at what it does. Not to mention Apple's entire framework is build around it. The new trend favoring Swift value types often leads to reinventing the wheel for the sake of premature optimization.
