title: App Groups not working (Swift)
body: <p>I am trying to pass data from my iPhone app to my Apple Watch app. I already have a working today extension widget (not sure if that requires app groups) but I cannot get the Apple Watch to read NSUserDefaults.</p>
  
  <p><strong>SET</strong></p>
  
  <p><code>let defaults:NSUserDefaults = NSUserDefaults(suiteName: "group.com.mySuite")</code></p>
  
  <pre><code>defaults.setObject(dates, forKey: "allDates")
  </code></pre>
  
  <hr>
  
  <p><strong>RETRIEVE</strong></p>
  
  <pre><code>var theDates = defaults.arrayForKey("allDates")
  </code></pre>
  
  <hr>
  
  <p>Nothing is crashing, but the NSUserDefaults call returns nil. Any suggestions?</p>
