Re: [The Java Posse] Any thoughts on Swift?

No, ARC is emphatically *not* garbage collection.  It's not new either,
Objectionable-C does it, as does auto_ptr in C++

There's a pretty accurate summary of the language on quora:
http://www.quora.com/How-does-Swift-Apple-Programming-Language-compare-with-other-modern-programming-languages

Though I'm upset that the most popular answer fails to mention the complete
lack of features for tackling concurrency!

Ok thanks for this link, interesting stuff there indeed :)
I guess I'll google a bit to see if I can understand the difference 
between ARC and a GC.

I notice the language features something they call "Automatic
Reference Counting". Is this the same as a Garbage Collector?

Re: [The Java Posse] Any thoughts on Swift?

[Carl Jokl]

I wonder about Swift in terms of performance of apps. Traditionally Games
companies use C++ for their games engines and on iOS just use the minimum
Objective-C to act as the glue to the operating system. For all Objective-C
apps then yes Swift will be a big improvement but for those where it was
kept to a minimum the difference may not be as dramatic.

I think it is good that Apple are moving away from Objective-C. Objective-C
did feel like a pet project of Steve Jobs and now that he is no longer
leading Apple they have the opportunity to replace it with something more
modern. It shouldn't be hard for swift to be more modern than Objective-C.

I expect as I will be developing mobile apps for my company I will have the
chance to give a first hand verdict of what I think of Swift. To be honest
it is kind of nice to think I may manage to dodge having to do so much
Objective-C as long as swift is backwards compatible with older versions of
iOS. I hope it is.

I'm unconvinced there is any point to syntactic support for concurrency.

Support concurrency in the runtime/bytecode and the libraries, absolutely.
But in the syntax? What does that buy you besides complicating the grammar?

Pretty sure c/c++ will remain the best cross platform option for a long
time.  Whatever promise of Java and related languages as providing cross
platform environments, this just never happened.  Closest would actually be
.net and friends, I believe.

Even the rise of such interesting projects as the unreal engine in the
browser seems to be taking advantage of the fact that the "cross platform"
portion is just a c dialect language.
