title: How to transfer a UIImage using Watch Connectivity
body: <p>How can I transfer an <code>UIImage</code> over <strong>WatchConnecitivity</strong> from the iPhone to the Apple Watch with no user interaction on the phone, and only loads because the watch calls for it programmatically. I need this because the image processing to create the <code>UIImage</code> uses logic unavailable in the Watchkit API, so it must be created from the phone. I have seem some examples of Watch Connectivity using:</p>
  
  <pre><code>func startSession() {
      session?.delegate = self
      session?.activateSession()
  }
  </code></pre>
  
  <p>However, I am new to watch kit and am confused on how to use this session manager, particularly to go from the watch to the device instead of the other way around like I see in apple documentation. Can someone please provide an example of how to do this on both the watch and the phone to call for a <code>UIImage</code> on the phone from the watch? </p>
