title: Update Xcode 10.1 to 10.2 on High Sierra 10.13.6
body: <p>I'm trying to update Xcode 10.1 to 10.2 on my High Sierra 10.13.6 version.</p>
  
  <p>The App Store window shows the update button, but the problem is after hitting that button, the circle on the upper-left corner is just rotating for hours and nothing else happens!</p>

  <p>Since the difference between the two versions is not that huge, the update naturally must be downloaded and installed after some time, but in effect it's not that way! </p>
  
  <p>How to solve that issue, please?</p>
