You're about to start a library or open-source thing that you want to be available to any iOS project. This is a handy guide for how to get set up.

#Setup

start a new Xcode project with "Empty Application"
project settings: verify name, devices (probably want Universal), Core Data (probably not), ARC (probably)
choose location, don't add to any workspace or project.

Ok, project exists. What now? Let's rip out all that boilerplate Xcode so graciously gave us.
