title: Getting started with Core Data
body: <p>I am having trouble understanding how Core Data works conceptually and in terms of code.</p>
  
  <p>I get that there is a coordinator and a context. I also get that there is state management. How do they work together?</p>
  
  <p>I don't understand how I can store, say, an image and a few strings as an object.</p>
  
  <p>Let's say I want to retrieve the image and the strings later. What do I do? </p>
  
  <p>Where do I save my state? How?</p>
  
  <p>What does my code look like? I would really appreciate a bare-bones code sample here, because I'm really confused.</p>
