title: How to build an IPA without signing in Xcode 8
body: <p>I have searched around SO and other places.  I have only found older versions of this answer that don't seem to work any more, and tons of other stuff that isn't even relevant in the latest version.</p>
  
  <p>Long story short, we have a developer providing an IPA to us, who doesn't want to join our developer group.  I told him to send us an unsigned IPA, but we couldn't get it figured out based on our old process.</p>
  
  <p>Has anyone done this yet, and would you mind sharing your method with the world?</p>
  
  <p>Thanks!</p>
