Reverse geocoding

VERSION 0.28.2

Reverse geocoding means converting coordinates to human-readable information. The most common use case is retrieving an address, but the Search SDK can also return more detailed information such as speed limits, postal codes, or road numbers.

Project setup

To use reverse geocoding, ensure the Search SDK has been added to the project.

  1. Configure the project as described in the project setup guide.

To access the reverse geocoding module, add TomTomSDKReverseGeocoder and TomTomSDKReverseGeocoderOnline modules to your project’s Podfile.

3target 'YourAppTarget' do
4 use_frameworks!
5 pod 'TomTomSDKReverseGeocoder', TOMTOM_SDK_VERSION
6 pod 'TomTomSDKReverseGeocoderOnline', TOMTOM_SDK_VERSION
  1. Install the dependencies by executing the following commands in the project directory:
    pod repo-art update tomtom-sdk-cocoapods
    pod install --repo-update

Initialing reverse geocoding

  1. Initialize the OnlineReverseGeocoder, which is the entry point for online reverse geocoding requests:
let reverseGeocoderApi = OnlineReverseGeocoder(apiKey: "YOUR_API_KEY")

Making a reverse geocoding call

Specify the reverse geocoding request parameters with the ReverseGeocoderOptions struct. The only mandatory parameter for the call is the CLLocationCoordinate2D of the position to get more information about. You can also set optional parameters to obtain more details about the location. A detailed description of all the parameters can be found in the Reverse Geocoding documentation.

1let coordinate = CLLocationCoordinate2D(latitude: 52.366425, longitude: 4.908645)
2let options = ReverseGeocoderOptions(
3 position: coordinate,
4 heading:,
5 radius:

Once the OnlineReverseGeocoder and ReverseGeocoderOptions objects are initialized, you can perform a reverse geocoding. Parameter completion: The completion closure is called after the response to the request has been processed. If no errors occurred, ReverseGeocoderResponse contains addresses that match the geocoding request.

Here is a sample reverse geocoder request:

1reverseGeocoderApi.reverseGeocode(options: options) { result in
2 // Here you can get the first address of the recognized place.
3 guard case let .success(response) = result,
4 let address = response.places.first?.place.address else {
5 return
6 }
