title: Can I install XCode 7.3 on OS X 10.10 Yosemite?
body: <p>I'm unable to upgrade my OS X to 10.11, due to reasons.
  XCode 7.3 seems to be the first XCode not to be compatible with Yosemite 10.10.</p>
  
  <p>Has anyone succeeded in getting XCode 7.3 to work on Yosemite?
  (What's the important update to XCode that <em>has</em> to make it uncompatible with Yosemite?)</p>
