title: Project won't run after name change
body: <p>I changed my project name with refractor on the side bar under Identity and type. Everything changed accordingly. However, my test target runs into an error:</p>
  
  <pre><code>clang: error: no such file or directory:'/Users/E/Downloads/GalaxyRun/GameTutorial/GameTutorial-Prefix.pch'
  clang: error: no input files
  Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1
  </code></pre>
  
  <p>What can I do to fix this? I am using iOS 8.</p>
