title: How to change the bundle identifier of an app in Xcode 5?
body: <p>Xcode 5 won't let me change the bundle identifier. The app name portion after <code>com.mycompany.</code> is greyed out.</p>
  
  <p>I created a bundle identifier in ITC which slightly differs and I want to use this new bundle identifier.</p>
  
  <p>Do I have to create a new Xcode project with the correct identifier?</p>
