`google-maps-ios-utils` used for maker clustering with `google-map-sdk` in `iOS`
google-maps-ios-utils open-source library contains classes that are useful for a wide range of applications using the Google Maps SDK for iOS.
The GMUClusterManager helps you manage multiple markers at different zoom levels. This means you can put a large number of markers on a map without making the map hard to read. When a user views the map at a high zoom level, the individual markers show on the map. When the user zooms out to a lower zoom level, the markers gather together into clusters, to make viewing the map easier.
