What kind of benchmark produced 220 times something faster than Python? My guess is that they did it on a mobile device and used an application like this: https://itunes.apple.com/us/app/python-2.7-for-ios/id4857298...

Can anybody find a link to the Swift guide that they mentioned in Keynote? All I see is Taylor Swift books.

LOL

So they copied this idea for the IDE? http://www.lighttable.com

Well, LightTable was inspired by Bret Victor's ideas. He worked at Apple earlier.

Swift has also pattern matching which I think is really awesome.

Earlier quoted context omitted.

I mean the inclusion of Python, seems so random to me It's supposed to be a "mainstream" scripting language. Also, it's an easy way for them to get favorable numbers for their presentation.

Yes. But what has that got to do with writing native apps?

It has everything to do with modern languages with powerful features.

Seems a lot more like a call back to the Smalltalk roots of Objective-C.

The demo from the WWDC keynote is quite impressive. Unfortunately, this site seems to have been slashdotted. (Basically, Swift is "Apple acquires their own LightTable.") It's touted as a language for parallelism. I'm curious about its concurrency primitives. Since distribution is shown as a top feature, I'm going to guess that it has an Erlang-like actor model.

Having ARC and not needing GC will end up being a big fundamental advantage for its parallelism story. (The problem with GC, is that one thread does work, then a GC thread comes along and possibly causes an additional cache miss.)
