I really don't get where the hate for Objective-C is coming from. Objective-C is definitely showing its age and I'm glad to see a new language that improves on it, but I really don't understand why the author's slagging it so much. I've worked in Java and Obj-C and I'd much rather work with the latter any day. I'm not saying it's perfect by any stretch, and I'm not saying it's objectively better than Java, just that there's a case for both. But I definitely don't think iOS would have better off if it had adopted Java as its language of choice instead of Objective-C.
