title: Build failed with xcode 10 beta
body: <p>I created a new project on Xcode beta and built it, It gives me the below build error.</p>
  
  <p>Encountered an error communication with <code>IBAgent-iOS</code> on <code>launchscreen.storyboard</code>.  </p>
  
  <p>The same storyboard error that I am getting when I try to build any sample projects built on Xcode 10 beta.</p>
  
  <p>Has anyone come across the same issue with Xcode 10 beta IDE?</p>
