title: Cocoapods and GGLContext error
body: <p>I've been reading thru all the help and other posts.. but I am obviously missing something.  I am using Cocoapods for the Google APIs.  I have installed them on my mac, and I am using the workspace that it created for my app.  The following code is giving me an error:</p>
  
  <pre><code>import UIKit
  import GoogleMobileAds
  
  class InformationViewController: UIViewController {
  
      @IBOutlet weak var bannerView: GADBannerView!
  
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          self.bannerView.adUnitID = GGLContext.sharedInstance().adUnitIDForBannerTest
          self.bannerView.rootViewController = self
          self.bannerView.loadRequest(GADRequest())
  
  
      }
  }
  </code></pre>
  
  <p>I receive an error in xcode that GGLContext is an unresolved identifier.</p>
