title: iOS App loader - what file type should be uploaded
body: <p>I have always been uploading iOS apps to appstore from XCode Organizer. That is pretty simple process. And we do not see any IPA or APP file is created. Now my client is trying himself to upload the app using app loader and is continuously asking for an IPA file. Now I have some specific questions - </p>
  
  <ol>
  <li>Does app loader exist now-a-days ? Is it a different program out of XCode?</li>
  <li>If it does, what file it takes from me to upload to appstore? An IPA?</li>
  <li>How do I create the file for appstore? Note that I have the distribution certificate and appstore provisioning files installed and set in my release configuration. And I am sure if I have tried with XCode it would upload already. But, client not allowing me to do that. He will do it using app loader.</li>
  </ol>
  
  <p>Special Notes - 
  1. Please do not give me links to an apple documentation, they do not talk about file type and how to create that. They always say "binary". Their doc titles does not reflect the content.
  2. Please do not show me the Ad Hoc build process, that is not what I am asking.
  3. Please only reply if you have used app loader before.</p>
