title: Error while build project Xcode says : "you don't have permission"
body: <p>I have downloaded one project from the internet and, when I am trying to run it/build it the XCode, XCode says :</p>
  
  <p>The file “PROJECT NAME” couldn’t be opened because you don’t have permission to view it.</p>
  
  <p>I have also put read/write permission to the project folder as well but still not working.</p>
