‘Obviously super complex’: evaluating software architecture as simple vs. easy
I have a problem with the characterization of VIPER, right out of the gate, as across-the-board “obviously super complex”, for a few reasons.

String is not a sufficient type: how using your type system can help you make better software
We deal with types, explicitly or implicitly—depending on our language of choice—every day. We often use them without even thinking about them, or we consider them an annoyance when we’re just trying to get something done. This brief talk presents an accessible metaphor to help explain that type sy…

Cocoa’s mutable-subclass pattern is an antipattern
We know we can’t mutate a mutable array while enumerating, and yes, we have to take care to avoid that. But wait a second—why is that *our* problem, as users of Apple’s Foundation framework?

Casting in Swift 1.2: a brief summary
Swift 1.2, in beta with Xcode 6.3, makes some changes to casting. Here’s how as, as?, and as! work:
* as is for guaranteed conversions. That is, use as when the compiler can type-check that the conversion is valid; and Swift won’t compile a as cast it …
IBOutlet declarations in Swift
Xcode’s default IBOutlet declarations are weak references to implicitly unwrapped optionals. This is wrong.

Let’s talk about Optionals
There has been much complaining that Swift's Optional type forces you to think about whether something may be nil at every use, but aren’t we thinking about that already, just maybe implicitly?
Swift’s optionals simply formally enforce the thinking we already must consider when writing (or …
