title: Can't Open .xip Xcode File
body: <p>I'm trying to install XCode 10.2 (most recent) through the developer.apple.com download. After downloading the .xip file, I try to open it like many other people have suggested, but it just creates a XCode_10.2.xip.cpgz file. I click on that and it creates an XCode_10. 2 2.xip and the cycle continues.</p>
  
  <p>Because of billing issues, I can't use the app store to download XCode.</p>
