title: What is Prefix.pch file in Xcode?
body: <p>So many developers are adding various convenience macros to the <code>Prefix.pch</code>. But my question is what is that <code>Prefix.pch</code> file. </p>
  
  <ul>
  <li><p>If i remove that <code>Prefix.pch</code> file from my <code>Xcode</code>, then will my application run? Or will it show any error? Or will it crash during build?</p></li>
  <li><p>How can i run my application without <code>Prefix.pch</code> file</p></li>
  </ul>
