In this episode I go over how I typically start new projects. I start off when an empty app template, do a bit of organization with groups to keep things tidy, introduce CocoaPods and a workspace, and wrap it up by setting up a map view controller using Storyboards on both the iPhone and the iPad. This project will be handy to use as a base for future episodes.

RestKit is a framework that aims to simplify the "plumbing" of your application to allow you to focus on your core features. In this screencast, I focus on fetching JSON from an API and mapping it onto our own objects using RestKit's mapping features.
