title: [CLLocationCoordinate2d]? does not have a member named subscript
body: <p>I am trying to get the latitude and longitude out of a CLLocationCOordinate2d that is in the first element of the array. I am getting an error with if let saying [CLLocationCoordinate2d]? does not have a member named subscript. Any ideas? Thanks!</p>
  
  <pre><code>    override func viewDidLoad() {
      super.viewDidLoad()
  
      weather.getLocationDataFromString("California USA", completion: { (location:[CLLocationCoordinate2D]?,error:NSError?) -&gt; (Void) in
          if location != nil{
              if let coordinate = location[0] as CLLocationCoordinate2D{ // ERROR: [CLLocationCoordinate2d]? does not have a member named subscript
                  println(coordinate.latitude)
  
          }
       }
  
  })
  }
  </code></pre>
