title: After implementing Google Analytics according to documentation, I am getting an Use Of Unresolved Identifier 'GGLContext' Error
body: <p>I have implemented the Google Mobile Analytics according to steps outlined on the <a href="https://developers.google.com/analytics/devguides/collection/ios/v3/?ver=swift" rel="noreferrer">Google Documentation Page</a>.  I have added the pod, I have the bridging header in place, I have downloaded the configuration file and imported the plist file provided.  However, when I insert the following code into my <code>appDelegate</code> file, I get the error <code>Use of Unresolved Identifier 'GGLContext'</code>.</p>
  
  <pre><code>        // Configure tracker from GoogleService-Info.plist.
      var configureError:NSError?
      GGLContext.sharedInstance().configureWithError(&amp;configureError)
      assert(configureError == nil, "Error configuring Google services: \(configureError)")
  
      // Optional: configure GAI options.
      var gai = GAI.sharedInstance()
      gai.trackUncaughtExceptions = true  // report uncaught exceptions
      gai.logger.logLevel = GAILogLevel.Verbose  // remove before app release
  </code></pre>
  
  <p>I have searched many forums and cannot find any solution.  I have even run <code>pod try Google</code> and looked at their example project and cannot see a difference.  Has any experienced this before (XCode 6.4, OSX 10.10.5, Swift 1)?  </p>
