title: Xcode Project error: xcodeproj cannot be opened because it is missing its project.pbxproj file
body: <p>I have been scratching my hair to solve this one. Here is what happened.</p>
  
  <p>I recently formatted my MAC and I synced all files back to it from my Dropbox account.</p>
  
  <p>For some reason I am getting this error each time I try to open any of my Xcode projects: </p>
  
  <p><code>xcodeproj cannot be opened because it is missing its project.pbxproj file.</code></p>
  
  <p>Now, I've found several threads on stack overflow that suggest different solutions and one common is to pewit the <code>.xcodeproj/project.pbxproj</code> file but when checking the content of my Xcode project I can't find such a file.</p>
  
  <p>I don't know what I can do anymore as my Xcode skills are highly limited and I would really be thankful if someone could put me in the right direction.</p>
  
  <p>Thanks!</p>
