Building UI with State Machines

A talk given at iOSoho in NYC on January 11, 2016.

This repository contains the slides and code I used to talk about building state machines with state machines.

The talk revolves around three main ideas:

1. Flow controllers: A way to pull view-controller-to-view-controller transition logic out of the individual view controllers, and into a single flow controller.
2. State machines: A collection of states and transitions. For the purpose of this talk, our states are view controllers, and our transitions are the transitions between them.
3. View Controller completion blocks: Thinking about view controllers as an asynchronous process, and giving them completion blocks. This lets us clean up the code and make it more readable.
