title: Google maps swift ios mapwithframe on GMSMapView error
body: <p>I am using the Google Maps iOS SDK(using swift) and after successfully running my program multiple times I decided to exit Xcode to resume working on my project later. After re-opening Xcode and trying to relaunch my project I get this error:</p>
  
  <blockquote>
    <p><strong>Terminating app due to uncaught exception
    'NSInvalidArgumentException', reason: '-[NSManagedObject tileCoords]:
    unrecognized selector sent to instance 0x7c037e90'</strong>.</p>
  </blockquote>
  
  <p>It is saying that there is no mapWithFrame method on the GMSMapView object, although I copied the sample code directly off of the Google maps SDK website.</p>
  
  <p>Could I receive a bit more guidance on handling this issue? Here is an image of the call stack <a href="https://i.stack.imgur.com/G6Tbm.png" rel="nofollow noreferrer">Image</a> and the line of the code it is blowing up on.</p>
  
  <pre><code>let camera = GMSCameraPosition.cameraWithLatitude(37.5784623,longitude:-77.42166750000001, zoom: 4)
  </code></pre>
  
  <p><em>Blows up here</em> ----> </p>
  
  <pre><code>mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera) 
  </code></pre>
