Ok, what about runtime support for older devices/iOS versions? They didn't say anything about it.

They said that they were accepting apps built with Swift for iOS 8 and OSX 10.10 so sounds like it won't work with older OS version. They weren't all that specific about it though so I could be wrong.

New language runs on Obj-C runtime. Maybe apps written in Swift can run smoothly on existing OS.

“You also don’t need to write semicolons at the end of every statement.”

Please. Please. PLEASE don't be whitespace delimited!

Still on an Objective-C runtime, so it's hard to see how the performance gains they claim are achievable, but otherwise having an interpreted version should be good for productivity.

The live REPL is totally out of Bret Victor, very impressive.

Bret Victor used to work in R&D at Apple, so that probably isn't a coincidence

Ugh, none of the links work. :( Can't get the ibook, can't view the "guides and reference", can't download xcode 6 beta.

"...we wondered what we could do without the baggage of C." Is that tongue in cheek? It's not even a particularly large, encumbered language, C.

It is when you have to maintain compatibility with it in your new shiny language that's based on it. C alone may not be particularly large or encumbered (though it does have that vexing parse), but as the foundation of other languages it can cause problems.
