In this case, I am actually featured prominently in this article--it isn't just that I know a lot about iOS or about Swift, but as the second half of this article and arguably the whole reason it was written was to show how to use Substrate (something I wrote) with Swift, I think it would be difficult to claim anything I say on the matter is "me too"--but even if it were someone totally random, I don't see why it should ever be considered a bad thing to direct people to more information :(.

(FWIW, I actually don't consider this article entirely correct: the information here implies that the symbols are available for all functions, and that was not my experience while on stage disassembling the WWDC app. I think I may need to parse the embedded Swift modules and provide new APIs for developers to look up methods out of the vtable, but before I go too crazy with that I am interested to see where the Swift-provided Swift.reflect ends up going.)
