title: Using core data with an existing single view application
body: <p>I'm trying to learn about Core Data and am following the "Locations" tutorial from Apple. One immediate stumbling block i've come across is that I have already started constructing the application that i want to use Core Data with. It is a single view application.</p>
  
  <p>What are the steps I need to take in order to utilize Core Data with this application? The tutorial says to select the checkbox "use core data for storage" when creating the project but there must be a way to enable core data after the project creation. </p>
  
  <p>I'd really appreciate some help. Thanks.</p>
