title: The document Main.storyboard requires Xcode 8.0 or later
body: <p>I downloaded Xcode beta and opened my existing project to see how it works with Xcode 8 beta (I opened Storyboard file from Xcode 8).</p>
  <p>Now when I open my project from Xcode 7.3 I am not able to open storyboard file , it gives me following error</p>
  <blockquote>
  <p>This version does not support documents saved in the Xcode 8 format.
  Open this document with Xcode 8.0 or later.</p>
  </blockquote>

  What should I do to revert back, as I want to continue working on Xcode 7.</p>
  <p>In Xcode 8 I was prompted to select device and I selected iPhone 6S, I think that part is somehow responsible for storyboard file not opening in Xcode 7</p>
