Maciej Matyjas from tackles messages buses and reactive programming models.

Apps are becoming more contextual and data-rich just as mobile chipsets are sporting more cores. Can enterprise architectures help manage this complexity and maximize performance? Or were these issues already solved by the functional programming paradigm in the 70s?

These days, mobile app developers are spoiled for choice when it comes to libraries that profess to harness all the magic of concurrency (without the heisenbugs) while also providing neat programming abstractions for managing state under a hail of events. The primary contenders in this space are message buses and reactive programming models. Each of these has representatives on the major mobile platforms. Lets take a tour and compare Otto, JavaRx on Android, as well as NSNotificationCenter and ReactiveCocoa. On the way, we will also talk through some earlier examples of pioneering technologies like QML and KVO.
