If you think about this as a small scale evolution it makes sense. On the other hand, I understand why the guy is unhappy. Apple os breaking compatibility for no good reason, mostly for promoting their new shiny things (like Swift), which does not bring that much to the table to justify breaking compatibility. Somebody pointed out in this thread that it is possible to roll with new platform that is compatible with the previous one and having new features at the same time. To summarize: platforms supposed to be stable, and backward compatible, only break compatibility when it is absolutely a must. Investing into a new stack is not cheap. I feel sorry for those who are at the mercy of Apple in this regard.
