Combine library

  • GoogleMapsPlatformCombine is a Swift library that integrates the Maps SDK for iOS and Places SDK for iOS with Apple's Combine framework.

  • This library provides Publishers for various SDK functionalities, allowing developers to leverage Combine's features for asynchronous event handling.

  • By using GoogleMapsPlatformCombine, developers can simplify their code and centralize event-processing logic for Google Maps and Places SDKs within their applications.

  • A practical example demonstrates subscribing to camera change events on a GMSMapView using the GMSMapViewPublisher and Combine's sink operator.

Combine is a framework for handling asynchronous events by combining event-processing operators. Combine makes your code easier to read and maintain by centralizing your event-processing code.

The GoogleMapsPlatformCombine library is a Swift library that returns Publishers for the Maps SDK for iOS and Places SDK for iOS so that you can take advantage of the rich set of Combine features.

Installation

For system requirements and installation instructions, see the GoogleMapsPlatformCombine library documentation on GitHub.

Example usage

The GoogleMapsPlatformCombine library includes the GMSMapViewPublisher class that contains publisher properties that let you subscribe to events emitted by the map.

Configure a GMSMapViewPublisher instance to subscribe to camera change events:

let publisher = GMSMapViewPublisher(mapView: mapView)
publisher.didChangeCameraPosition.sink { cameraPosition in
  print("Camera position at \(cameraPosition.target)")
}
