title: Storing blobs in external location using built-in CoreData option
body: <p>I have managed objects that have image properties. Since storing large blobs in CoreData is a bad idea, I'm trying to use the built-in CoreData option "<strong>Store in External Record File</strong>" which you can see in the Data Model Inspector. </p>
  
  <p>Despite enabling this option, I do not see any image data being stored externally. Judging by the size, it seems like they are still being saved in the sqlite file. What is the issue?</p>
