title: Reduce debug output from CoreData?
body: <p>I'm working on a iOS/macOS project where I'm using CoreData. It works fine, but it outputs enormous amounts of debugging info to the Console. This makes the Console unusable, since my print statements are buried in all the CoreData related stuff.</p>
  
  <p>I have a pretty simple CoreData setup with fetching of some data, so these are not errors, just general event logs it seems. I have the same results on other projects I have used CoreData.</p>
  
  <p><strong>Any way to reduce/remove this logging to the console?</strong></p>
  
  <p>Some sample data (<a href="https://gist.github.com/eivindml/75f9f3cbe76e1cef7c3f2a33e39c9c85" rel="noreferrer">all data here</a>):</p>
