title: Why Google PlacePicker pickPlace crashes on EXC_BREAKPOINT Swift3 IOS10
body: <p>I upgraded XCode to version 8.0 and started to convert my project to Swift3. I use via PODS Google libraries like GoogleMaps, GooglePlaces and GooglePlacePicker. Just like you would guess, everything worked like a charm before update. After update there was hundreds of fix-items to be solved, nothing special here, I managed to solve them, atlas for now.</p>
  
  <p>Basic platform in project is IOS 10.</p>
  
  <p>Problem is that GooglePlacePicker just stopped working and I just cant figure out what is problem. I run it on the Iphone 6 device. PickerView does not ever show up and after a short timeout program crashes and points to the callback function. It does not matter what you have inside the callback function. Anyone has any clues? </p>
  
  <p>See the break point here</p>

  <p>My code:</p>
  
  <pre><code>    let center = place.coordinate
      let northEast = CLLocationCoordinate2DMake(center.latitude + 0.001, center.longitude + 0.001)
      let southWest = CLLocationCoordinate2DMake(center.latitude - 0.001, center.longitude - 0.001)
      let viewport = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest)
      let config = GMSPlacePickerConfig(viewport: viewport)
      placePicker = GMSPlacePicker(config: config)
  
  
      placePicker?.pickPlace(callback: { (place: GMSPlace?, error: NSError?) -&gt; Void in
  
      if let error = error {
              print("Pick Place error: \(error.localizedDescription)")
              return
          }
  
          if let place = place {
              print("Place name \(place.name)")
              print("Place address \(place.formattedAddress)")
              print("Place attributions \(place.attributions)")
          } else {
              print("No place selected")
          }
      } as! GMSPlaceResultCallback)
  </code></pre>
  
  <p>If any advices available, would be appreciated. And I dont think its up the API key, because Autocomplete works still.</p>
