I also covered some of this (in fact, last I saw this article, much more than is here, but I can't see the article right now because it is just saying there is a database error) in my talk at AltConf (during WWDC), where I used Hopper and Cycript (my Objective-C/JavaScript hybrid debug REPL) to demonstrate the layout of a Swift object (as well as taking some questions afterwards from the audience).
Grandparent was probably out of line (saurik's comment provided useful information that went beyond me too-ism), but I can understand why one would be wary. Its hard to keep up with who is legit, and there has been a lot of me tooism lately.
At least no one has started writing any horrible books on Swift yet.
I am not certain I understand the problem with "me too-ism". Hacker News is a discussion forum: if I go into the comments on a post, what I am expecting to find is more information about the topic written by other people... if someone links to a related project or an article with more detail, I don't see how that's a problem.
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.)
I did get that, but you did say that people might should be "wary", and I found it a little confusing as I don't really understand the concept of this "me tooism" as a problem. (I also was addressing both your comment about it being difficult to keep track of people who are "legit" by pointing out my direct connection in the article, but that response was more to the thread as a whole.)
