Feels like they looked at a bunch of programming languages, took all their favorite features, and then put them into one which still sits on top of the ObjC runtime. And then added some Apple syntactic craziness. For example: var apples = 3; // mutable let oranges = 5; // immutable let summary = "I have \(apples) apples and \(oranges) oranges";
So it looks like the language isn't open source and won't target non-Apple runtimes? I'm not trying to troll, I just think that it's a pity that Apple tends to limit the ecosystem and applications of its otherwise-great languages. Building against LLVM ought to make it fairly trivial to make this cross-platform.

Question: It sounds like the Xcode 6 beta is available on the dev center but I can't find it. Do you have to be a paying developer to have access to it, or does anyone know if it's going to be made available for free to (unpaid) registered developers?

You can see first chapter of the book here http://imgur.com/a/AuzGw I've uploaded it just now
I just skimmed the tour, and my impression is: Swift is a compiled, Objective-C compatible Javascript-alike with an ObjC-like object model, generics, and string interpolation. No exceptions. Based on LLVM and appears to inherit the same data structures as Cocoa apps (Dictionaries, Arrays, &c). It feels very lightweight, sort of like an analog to what Javascript is in a browser.
Unicode variables, I love it: let 🐶🐮 = "dogcow" Moof!
You can do this in C# (and presumably other languages). I've seen people using Greek symbols in mathy code before. It's kind of fun.
"The company says that Swift apps are significantly faster than Objective-C apps, outperforming them by over 93x." With a graph showing ObjC at 127x faster than Python, Swift 220x faster than Python. Thus the conclusion is 220 - 127, Swift is 93x faster than ObjC. Someone needs to resit their GCSEs.

> language website: http://swift-lang.org/ Nope, completely different. Really scummy of Apple to just nick the name of an existing language for their new one, it's been five minutes and people are already confused.
Looks nice. But I wish one could interop it with C++ like Obj-C. As it is now I won't be able to use Swift because of that :(
