title: PubNub - iOS - Carthage only?
body: <p>Question for someone who's quite fresh with PubNub and iOS-Swift,</p>
  
  <p>as of today can you put PubNub in a project, entirely, absolutely <strong><em>not using</em></strong> cocoapods in any way?  So, pure Carthage?</p>
  
  <p>(PubNub's own doco is a little confused on the matter, at a quick glance.)</p>
  
  <p>(Strictly iOS 10, no legacy)</p>
