Thought much about Swift yet? What are the cool things in your opinion? What do you think of its perspective on OOP?

Already lots of discussion Twitter about the design/performance tradeoffs and subtleties of using classes vs. structs, etc.

got a couple links?

@maxpow4h Curious: why do you use classes instead of structs for implementations in swiftz?

My perspectives on OO broadly align with this talk; I think Swift expresses those concepts nicely: destroyallsoftware.com/talks/boundari

One more question - got a (hopefully concise) bit of Swift code handy that illustrates this?

1

You mean the preference for structs and simple data types over classes?

I like how you phrased that, yeah! Roughly how "Swift's idea of OO" aligns with Gary's talk

I'm not as sophisticated about this as, say,

@andy_matuschak

, but there is an interesting discussion here: developer.apple.com/library/prerel

I don't have such a code sample, but that does sound like a good thing for me to write up.

Tried to watch that talk but have to admit I got a bit lost in the thick cloud of unit testing disquisition.

I get that but do try to stick with it if you can: the unit tests independently expose a broader design problem…

My sense is that I intuitively agree with your sensibility on OO, but I'd love to see more concrete discussion too.

And, yes, I'll see about a more concrete discussion. :)

That would be lovely :)
