title: Where is the Enable Core Data Button in Xcode?
body: <p>I'm sorry, this is simply driving me crazy. I was trying to follow the answer for <a href="https://stackoverflow.com/questions/19432058/no-managedobjectcontext-defined-in-my-appdelegate/19432410#19432410">this</a> StackOverflow question, but I simply can't find the <strong>Use Core Data</strong> button anywhere in Xcode 5 or 6.</p>
  
  <p>Can anyone help me with this?</p>
