title: How to add configurations to Xcode?
body: <p>There are no other way, I search a lot. In XCode 3 this is easy, but now..</p>
  
  <p>In the screen above, I have the <strong>Build Configuration</strong>, so I can chose if I want:</p>
  
  <ul>
  <li>Debug</li>
  <li>Release</li>
  </ul>

  <p>This 2 kind of config, have their own config in "Build Settings" tabs (in targets config). To create I third one, the <strong>Distribution</strong>, reading <a href="http://developer.apple.com/ios/manage/distribution/index.action" rel="noreferrer">here,</a> it show this image in XCode 3 <img src="https://i.stack.imgur.com/NuM5E.jpg" alt="boring xcode 3"></p>
  
  <p><strong>Where I can do the same in XCode 4????</strong></p>
  
  <p>edit->
  Only create a new Schema didn't work, like this is a config in "Build Settings" tag of Targets. I can chose a config for "Debug" and "Release", but, and for I third one?</p>
