In my experience, it's difficult to go through because it's so comprehensive and thorough, and I guess it has to be because it has to assume the lowest common denominator audience. Personally I'd like a shorter guide that assumes you know a few languages (C#, ObjC, JS, Java) and skips a bunch of the tedium of how programming languages work in general and gets right to what's different about Swift. It may seem like it does that, but look at their page about control flow[1] and tell me it's not an unreasonably long-winded way of explaining switch, for, for-in, while, break, continue, and if.

I agree but Swift is a new enough language that I'm not sure such a resource exists yet. When I learned Swift I just skimmed through the parts that weren't interesting and that worked for me. It was a good overview of the language.

As an aside, the book, Advanced Swift, by the objc folks is fantastic but assumes you already know Swift. It's not what you're looking for, but something to move onto after you grasp the basics.

Maybe there is room for a publisher that makes books for people that already know how to program?
