title: Parse SaveEventually Issue in iOS Swift
body: <p>I'm facing an issue with save eventually.</p>
  
  <p>I'm retrieving an object from <strong>Parse</strong> the object contains a pointer for a User.

  <p>I'm trying to update the object and save it with a different user.</p>
  
  <pre><code>object.incrementKey("Likes")
  object.addObject((PFUser.currentUser()?.objectId)!, forKey: "LikesUsers")
  object.saveEventually()  
  </code></pre>
  
  <p>it works once or twice and then it generates this Error and the app crashes :</p>
  
  <blockquote>
    <p>Caught "NSInternalInconsistencyException" with reason "User cannot be
    saved unless they have been authenticated via logIn or signUp</p>
  </blockquote>
  
  <p><strong>I think the user pointer shouldn't be saved ! and I would like to know if there is any function to tell Parse to not save the User and modify the dirty value.</strong></p>
