Closures for fun and profit
This is the first in a series of short posts addressing easy things you might not know about. I'm going to try interleaving these thing the long-form major effort-posts.
Many people don't know that you can explicitly specify capture lists for closures in Swift.
A closure closes over . . .
I Want a Type-alee-uss-ess-ess for Christmas
Associated Types Series
Sometimes I think type theory is deliberately obtuse and all those functional programming hipster kids are just bull-shitting as if they understood one word of it. Really? You have a 5,000 word blog . . .
Or the case of the disappearing values
While trying to create a new view controller in Swift I ran into a curious problem with initialization. The class was a relatively simple subclass of
UITableViewController containing a property
var values:[String] and an initializer

super.init(style:UITableViewStyle) initializer. So far, so . . .
Interop is easy right up until it isn't
Swift and Objective-C use the same runtime. They use the same ARC memory management. They certainly interoperate far more than most languages except perhaps ones targeting the CLR. You might be forgiven for thinking that writing new classes in Swift would be easy, but there are several gotchas you might encounter:

Ah for those carefree days
Welcome to another glorious Swift post, brought to you from foggy outer sunset in San Francisco. I'm working full time on iOS and loving every minute of it.
Today, let's talk about optional method chaining and
respondsToSelector. Normally in Objective-C land, we have to do a little dance any time we want to handle selectors . . .
Warning: not a technical post
I hate posting business-y kind of stuff so I'll keep these kinds of non-technical posts infrequent.
We're a startup . . .
In the lifecycle of any release there comes a time when known bugs are far better than unknown bugs you accidentally introduce. Obviously Apple has reached that point with iOS 8, the SDK, Xcode 6, and Swift. The version shipping in the Xcode 6 GM is certainly a good release for Swift, but did you know there is a newer version of the compiler . . .
