title: Error when using GMSPlacesClient in swift using Xcode 6.4
body: <p>Im following the Google API documentation and attempting to find places around the current device. I am trying to use the GMSPlacesClient.currentPlaceWithCallback.</p>
  
  <p>The documentation example is </p>
  
  <pre><code>GMSPlacesClient.currentPlaceWithCallback({ (placeLikelihoods: GMSPlaceLikelihoodList,error) -&gt; Void in
          if error != nil {
              println("Current Place error: \(error.localizedDescription)")
              return
          }
  
          for likelihood in placeLikelihoods.likelihoods {
              if let likelihood = likelihood as? GMSPlaceLikelihood {
                  let place = likelihood.place
                  println("Current Place name \(place.name) at likelihood \(likelihood.likelihood)")
                  println("Current Place address \(place.formattedAddress)")
                  println("Current Place attributions \(place.attributions)")
                  println("Current PlaceID \(place.placeID)")
              }
          }
      })
  </code></pre>
  
  <p>However it is failing build with error Cannot invoke 'currentPlaceWithCallback' with an argument list of type '((GMSPlaceLikelihoodList, _) -> Void)'</p>
  
  <p>Suggestions please..Thanks</p>
