With the Maps SDK for iOS, you can add maps based on Google maps data to your application. The SDK automatically handles access to the Google Maps servers, map display, and response to user gestures such as clicks and drags. You can also add markers, polylines, ground overlays and info windows to your map. These objects provide additional information for map locations, and allow user interaction with the map.

When using the SDK you need to comply with the Google Maps Platform Terms of Service and ensure that your app complies with applicable laws. Note that when using the SDK, your application name and version, authentication information and a cross-application anonymous identifier is automatically sent with each request.
