title: Can I delete entire developer folder under Library
body: <p>I need to update my Xcode 8.2 to Xcode 9. I upgraded my OS to macOs High Sierra 10.13. Then I went to Mac App Store and tried downloading it and the update button keeps spinning for infinity. I searched google and stackoverflow and apparently this is a known bug going back ages. One of the solution suggested that I should delete Xcode application and then try the download/update button again in App Store.</p>
  
  <p>See Here <a href="https://stackoverflow.com/questions/43065475/unable-to-update-to-xcode-8-3">Unable to update to Xcode 8.3</a></p>
  
  <p>So, if I am going to completely remove Xcode application from my computer then I was thinking I should cleanup my comp and remove unnecessary Xcode files that I don't need and they will be recreated upon a new install. These are huge folders and looks like related to my Xcode development activities. Can I safely delete them?</p>
