title: How to support multiple watches for iOS 9.3 and watchOS 2.2
body: <p>Having trouble figuring out how to update my watch and iOS apps for watchOS 2.2 in order to support multiple watches.</p>
  
  <p>I know there are new functions that must be implemented primarily on the iOS app side, but also on the watch extension according to the Developer Library: </p>
  
  <pre><code>session:activationDidCompleteWithState:error:
  
  sessionDidBecomeInactive:
  
  sessionDidDeactivate:
  </code></pre>
  
  <p>I'm not really sure how to do it and what code these functions should run.</p>
