You're showing some incredible arrogance here by not addressing my other points. You fail to address the point how specifically the Swift language (not the Swift runtime) is so innovative that it enables fast apps on resource constrained devices. Because I can name dozens more languages that could do the same with native access to the Apple runtime.

How about naming one that actually now does the same with the native access to any GUI resource constrained platform? F# certainly can't avoid the graph quoted. The y axis is the slowdown as soon as there isn't enough memory. The point you yourself claim that you don't understand, so how can we discuss anything further? I actually wrote my comments assuming that the people who'd discuss would understand the issues I assumed to be well-known and thoroughly documented among other places in the Drew Crawford's article.

Don't hang me up on a figure of speech. It's frustratingly rude. I do understand how memory management relates to fluid applications. I don't understand how that point relates to Swift's innovativity, and you give the impression that you don't either. Please at least have the courtesy to show how the Swift language has an innovation that allows for responsive UIs. There are dozens of languages that are or can be reference counted.
