title: Why are there recovered references in my xcode project file?
body: <p>I have a react native app and just noticed that a few lines were added for <code>Recovered References</code> in my <code>project.pbxproj</code> file in Xcode.</p>
  
  <p>I don't remember adding or deleting any references and the recovered references show libraries that I normally use.  I'm hesitant to check in the local changes to git without knowing what these changes were.  Should I just discard these changes?</p>
  
  <p>Can someone explain why these lines might be added if I didn't add or remove these packages myself?  Does this mean some references were deleted to later be recovered?  The only thing I can think of is that I ran react-native link, would that have made these changes?</p>
  
  <p>This line was added</p>
