SpriteKit with Objective-C, and React Your Cocoa

Details
Bill Davis will kick off the night with a brief intro to SpriteKit using Objective-C. Bill writes:
" "Sprite Kit is an exciting new framework for making 2D games that comes built-in to iOS 7. It has sprite support, support for cool special effects like videos, filters, and masking, an integrated physics library, and a lot more." -- Ray Wenderlich
Since I believe in every application developer there is a frustrated game programmer, I want to give a brief introduction to game programming with Sprite KIt with the simple example of bouncing a ball."
Then Tami Wright will give a talk on Reactive Cocoa. Here is what Tami will cover:
"Reactive design patterns and programming are gaining traction in software engineering disciplines such as in scalable and distributed systems engineering, and via languages such as Scala--but is there a place for reactive programming in Cocoa and iOS development? Yes, most definitely there is! Let's take an investigative trip into real-world problems presented in every day Cocoa development that can be solved more effectively by taking reactive design patterns and applying them. From dealing with and recovering from service failure, to handling and observing the future results and aggregation of multi-threaded tasks in a more straightforward manner; from rolling your own (RYO) reactive code utilizing newer constructs such as blocks in Objective-C and closures in Swift, to doing the same utilizing new and cutting edge libraries and frameworks such as ReactiveCocoa...by the end of the hour the speaker will have the audience marching out the door well-equipped with paradigms, approaches, custom code (yes, you read that right--CUSTOM CODE), tools, libraries, and frameworks to make their jump and transition into reactive Cocoa development painless, seamless, and, well...reactive."
