Protocol-Oriented Programming in Swift

Speaker: David Abrahams. (Tech lead for Swift standard library)

• "Crusty" is an old-school programmer who doesn't trust IDE's, debuggers, programming fads. He's cynical, grumpy.

• OOP has been around since the 1970's. It's not actually new.

• Classes are Awesome

  • Encapsulation
  • Access control

  func animateWithDuration(duration: NSTimeInterval, animations: () -> Void, completion: (() -> Void)?) {
    animateWithDuration(duration, animations: animations)
    let delay = dispatch_time(DISPATCH_TIME_NOW, Int64(duration * Double(NSEC_PER_SEC)))
    dispatch_after(delay, dispatch_get_main_queue()) {
      completion?()
    }

A simple idea using the trick of keypath(...) derived from libextobjc and ReactiveCocoa and null-object pattern.

Create a category method in NSObject and define a macro PropertyNameForClass().
