Yes, that article is nearly four years old. Since then, Swift has evolved considerably.

Steve Troughton-Smith has tweeted recently about his work in converting all of his apps to Swift over the last year [1]. "I will remember ObjC and the times we had together fondly, but after a year of being Swift-only I prefer making apps with it" [2]. "I also wouldn’t change the timeline in which I adopted Swift ... I don’t feel I lost out on anything positive by waiting" [3].

Marco Arment has talked about using Swift in new development for Overcast, although I don't believe he's rewriting existing code. He seems more open to Swift these days than when that article was written. (Can't find a quotable source at present)

Marcel Weiher has continued working on a language now called Objective-S, which sounds like the "more Smalltalk-y" language that other commenters have wished for: "Objective-S includes an Objective-C compatible runtime model, but using a much simpler and consistent Smalltalk-based syntax." [4]
