You can use the Consumer SDK to build and run a basic consumer app integrated with On-demand Rides and Deliveries Solution backend services. You can create a Trip and Order Progress app that can display an active trip, respond to trip updates, and handle trip errors.
Because the Consumer SDK has a modular architecture, you can use the parts of the API that you want to use for your particular app and integrate them with your own APIs, backend services provided by the Fleet Engine, and additional APIs of the Google Maps Platform.
Minimum system requirements
Project configuration
You can configure the Consumer SDK by using CocoaPods.
Use CocoaPods
To configure the Consumer SDK using CocoaPods, you need the following items:
- The CocoaPods tool: To install this tool, open the Terminal and run the
following command.
shell sudo gem install cocoapods
Refer to the CocoaPods Getting Started guide for more details.
Create a Podfile for the Consumer SDK and use it to install the API and its dependencies. First, create a file named Podfile in your project directory. This file defines your project's dependencies. Then edit the Podfile and add your dependencies. Here is an example which includes the dependencies:
source "https://github.com/CocoaPods/Specs.git" target 'YOUR_APPLICATION_TARGET_NAME_HERE' do pod 'GoogleRidesharingConsumer' end
Save the Podfile. Open a terminal and go to the directory containing the Podfile:
cd <path-to-project>
Run the pod install command. This will install the APIs specified in the Podfile, along with any dependencies they may have.
pod install
Close Xcode and then open (double-click) your project's .xcworkspace file to launch Xcode. To open the project later, use the .xcworkspace file.
Install the XCFramework
An XCFramework is a binary package that you use to install the Consumer SDK. You can use this package on multiple platforms, including machines using the M1 chipset. This guide shows how to manually add the XCFramework containing the Consumer SDK to your project and configure your build settings in Xcode.
Unpack the source files that you received from Google.
Start Xcode and either open an existing project, or create a new project. If you're new to iOS, create a new project and select the iOS App template.
Create a Frameworks group under your project group if one does not exist already.
Drag the
gRPCCertificates.bundle
file included in theResources
directory of the zip containing the XCFramework into the top level directory of your Xcode project. When prompted, select Copy items if needed.To install the Consumer SDK, drag the
GoogleRidesharingConsumer.xcframework
file into your project underFrameworks, Libraries, and Embedded Content
. When prompted, select Copy items if needed.Select your project from the Project Navigator, and choose your application's target.
Open the Build Phases tab, and in Link Binary with Libraries, add the following frameworks and libraries if they are not already present:
Accelerate.framework
CoreData.framework
CoreGraphics.framework
CoreImage.framework
CoreLocation.framework
CoreTelephony.framework
CoreText.framework
GLKit.framework
ImageIO.framework
libc++.tbd
libz.tbd
Metal.framework
OpenGLES.framework
QuartzCore.framework
SystemConfiguration.framework
UIKit.framework
Choose your project, rather than a specific target, and open the Build Settings tab. In the Other Linker Flags section, add
‑ObjC
for both debug and release. If these settings are not visible, change the filter in the Build Settings bar from Basic to All.
Alpha/Beta SDK versions
To configure the Alpha or Beta versions of the Consumer SDK using CocoaPods for iOS you need the following items:
The CocoaPods tool: To install this tool, open the Terminal and run the following command.
sudo gem install cocoapods
Refer to the CocoaPods Getting Started guide for more details.
Your development account on the Google access list. The pod repository of the Alpha and Beta versions of the SDK are not public source. To access those versions, contact the Google Customer Engineer. The engineer adds your development account to the access list and then sets a cookie for authentication.
After your project is on the access list, you can access the pod.
Create a Podfile for the Consumer SDK for iOS and use it to install the API and its dependencies: Create a file named Podfile in your project directory. This file defines your project's dependencies. Edit the Podfile and add your dependencies. Here is an example which includes the dependencies:
source "https://cpdc-eap.googlesource.com/ridesharing-consumer-sdk" source "https://github.com/CocoaPods/Specs.git" target 'YOUR_APPLICATION_TARGET_NAME_HERE' do pod 'GoogleRidesharingConsumer' end
Save the Podfile. Open a terminal and go to the directory containing the Podfile:
cd <path-to-project>
Run the pod install command. This will install the APIs specified in the Podfile, along with any dependencies they may have.
pod install
Close Xcode, and then open (double-click) your project's .xcworkspace file to launch Xcode. From this time onwards, you must use the .xcworkspace file to open the project.
Application integration
Provide authentication token
When your Consumer app requests trip updates from Fleet Engine,
the requests must include valid access tokens. To authorize and
authenticate these requests, the Consumer SDK calls your object conforming to
the GMTCAuthorization
protocol. The object is responsible for providing the required access token.
As the app developer, you choose how tokens are generated. Your implementation should provide the ability to do the following:
- Fetch an access token, possibly in JSON format, from an HTTPS server.
- Parse and cache the token.
- Refresh the token when it expires.
For details of the tokens expected by the Fleet Engine server, see Creating a JSON Web Token (JWT) for authorization.
The provider ID is the same as Google Cloud Project ID. For more information, see Getting Started with Fleet Engine.
The following example implements an access token provider:
Swift
/*
* SampleAccessTokenProvider.swift
*/
import GoogleRidesharingConsumer
private let providerURL = "INSERT_YOUR_TOKEN_PROVIDER_URL"
class SampleAccessTokenProvider: NSObject, GMTCAuthorization {
private struct AuthToken {
// The cached trip token.
let token: String
// Keep track of when the token expires for caching.
let expiration: TimeInterval
// Keep track of the trip ID the cached token is for.
let tripID: String
}
enum AccessTokenError: Error {
case missingAuthorizationContext
case missingData
}
private var authToken: AuthToken?
func fetchToken(
with authorizationContext: GMTCAuthorizationContext?,
completion: @escaping GMTCAuthTokenFetchCompletionHandler
) {
// Get the trip ID from the authorizationContext. This is set by the Consumer SDK.
guard let authorizationContext = authorizationContext else {
completion(nil, AccessTokenError.missingAuthorizationContext)
return
}
let tripID = authorizationContext.tripID
// If appropriate, use the cached token.
if let authToken = authToken,
authToken.expiration > Date.now.timeIntervalSince1970 && authToken.tripID == tripID
{
completion(authToken.token, nil)
return
}
// Otherwise, try to fetch a new token from your server.
let request = URLRequest(url: URL(string: providerURL))
let task = URLSession.shared.dataTask(with: request) { [weak self] data, _, error in
guard let strongSelf = self else { return }
guard error == nil else {
completion(nil, error)
return
}
// Replace the following key values with the appropriate keys based on your
// server's expected response.
let tripTokenKey = "TRIP_TOKEN_KEY"
let tokenExpirationKey = "TOKEN_EXPIRATION"
guard let data = data,
let fetchData = try? JSONSerialization.jsonObject(with: data) as? [String: Any],
let token = fetchData[tripTokenKey] as? String,
let expiration = fetchData[tokenExpirationKey] as? Double
else {
completion(nil, AccessTokenError.missingData)
return
}
strongSelf.authToken = AuthToken(token: token, expiration: expiration, tripID: tripID)
completion(token, nil)
}
task.resume()
}

Map view integration
Initialize the map view
The following example shows how to initialize GMTCMapView
.
Swift
/*
* MapViewController.swift
*/
class ViewController: UIViewController, GMTCMapViewDelegate {
private var rideSharingMap: GMTCMapView?
override func viewDidLoad() {
super.viewDidLoad()
self.rideSharingMap = GMTCMapView(frame: UIScreen.main.bounds)
self.rideSharingMap.delegate = self
self.rideSharingMap?.settings.myLocationButton = true
self.view.addSubview(self.rideSharingMap!)
...
}
Objective-C
/*
* MapViewController.h
*/
@interface MapViewController : UIViewController<GMTCMapViewDelegate>
...
@end
/*
* MapViewController.m
*/
@implementation MapViewController
- (void)viewDidLoad {
[super viewDidLoad];
...
self.mapView = [[GMTCMapView alloc] init];
self.mapView.settings.myLocationButton = YES;
self.mapView.delegate = self;
...
}
...
@end
Handle map view events
The following example shows how to implement a delegate to handle customer state events.
Swift
func mapViewDidInitialize(_ mapview: GMTCMapView) {
// Handle the update to the state of the map view to browsing.
}
func mapView(_ mapView: GMSMapView, didTapConsumerMarker mapMarker: GMSMarker, markerType: GMTCMapViewMarkerType) -> Bool {
// Handle the mapView marker was tapped.
}
Objective-C
/*
* MapViewController.m
*/
#pragma mark - GMTCMapViewDelegate implementation
// Handle state update of map view.
- (void)mapViewDidInitializeCustomerState:(GMTCMapView *)mapview {
// Handle the update to the state of the map view to browsing.
}
- (void)mapView:(GMSMapView *)mapView
didTapConsumerMarker:(nonnull GMSMarker *)mapMarker
markerType:(GMTCMapViewMarkerType)markerType {
// Handle the mapView marker was tapped.
}
Journey sharing
Start a new trip when view did load
The following example shows how to start a journey sharing immediately after the
view loads. You can gather all user inputs such as drop off and pickup locations
from a ViewController
, and then create a new ViewController
to start the
journey sharing directly.
Swift
/*
* MapViewController.swift
*/
override func viewDidLoad() {
super.viewDidLoad()
...
self.mapView = GMTCMapView(frame: UIScreen.main.bounds)
self.mapView.delegate = self
self.view.addSubview(self.mapView)
}
func mapViewDidInitializeCustomerState(_: GMTCMapView) {
self.mapView.pickupLocation = self.selectedPickupLocation
self.mapView.dropoffLocation = self.selectedDropoffLocation
self.startConsumerMatchWithLocations(
pickupLocation: self.mapView.pickupLocation!,
dropoffLocation: self.mapView.dropoffLocation!
) { [weak self] (tripName, error) in
guard let strongSelf = self else { return }
if error != nil {
// print error message.
return
}
let tripService = GMTCServices.shared().tripService
// Create a tripModel instance for listening the update of the trip
// specified by this trip name.
let tripModel = tripService.tripModel(forTripName: tripName)
// Create a journeySharingSession instance based on the tripModel
let journeySharingSession = GMTCJourneySharingSession(tripModel: tripModel)
// Add the journeySharingSession instance on the mapView for UI updating.
strongSelf.mapView.show(journeySharingSession)
// Register for the trip update events.
tripModel.register(strongSelf)
strongSelf.currentTripModel = tripModel
strongSelf.currentJourneySharingSession = journeySharingSession
strongSelf.hideLoadingView()
}
self.showLoadingView()
}
Objective-C
/*
* MapViewController.m
*/
- (void)viewDidLoad {
[super viewDidLoad];
...
self.mapView = [[GMTCMapView alloc] init];
self.mapView.delegate = self;
[self.view addSubview:self.mapView];
}
// Handle the callback when the GMTCMapView did initialized.
- (void)mapViewDidInitializeCustomerState:(GMTCMapView *)mapview {
self.mapView.pickupLocation = self.selectedPickupLocation;
self.mapView.dropoffLocation = self.selectedDropoffLocation;
__weak __typeof(self) weakSelf = self;
[self startTripBookingWithPickupLocation:self.selectedPickupLocation
dropoffLocation:self.selectedDropoffLocation
completion:^(NSString *tripName, NSError *error) {
__typeof(self) strongSelf = weakSelf;
GMTCTripService *tripService = [GMTCServices sharedServices].tripService;
// Create a tripModel instance for listening to updates to the trip specified by this trip name.
GMTCTripModel *tripModel = [tripService tripModelForTripName:tripName];
// Create a journeySharingSession instance based on the tripModel.
GMTCJourneySharingSession *journeySharingSession =
[[GMTCJourneySharingSession alloc] initWithTripModel:tripModel];
// Add the journeySharingSession instance on the mapView for updating the UI.
[strongSelf.mapView showMapViewSession:journeySharingSession];
// Register for trip update events.
[tripModel registerSubscriber:self];
strongSelf.currentTripModel = tripModel;
strongSelf.currentJourneySharingSession = journeySharingSession;
[strongSelf hideLoadingView];
}];
[self showLoadingView];
}
Cancel the active trip
The following example shows how to reset the current active trip.
Swift
/*
* MapViewController.swift
*/
func cancelCurrentActiveTrip() {
// Stop the tripModel
self.currentTripModel.unregisterSubscriber(self)
// Remove the journey sharing session from the mapView's UI stack.
self.mapView.hide(journeySharingSession)
}
Objective-C
/*
* MapViewController.m
*/
- (void)cancelCurrentActiveTrip {
// Stop the tripModel
[self.currentTripModel unregisterSubscriber:self];
// Remove the journey sharing session from the mapView's UI stack.
[self.mapView hideMapViewSession:journeySharingSession];
}
Listen for trip updates
The following example shows how to register the tripModel
callback.
Swift
/*
* MapViewController.swift
*/
override func viewDidLoad() {
super.viewDidLoad()
// Register for trip update events.
self.currentTripModel.register(self)
}
Objective-C
/*
* MapViewController.m
*/
- (void)viewDidLoad {
[super viewDidLoad];
// Register for trip update events.
[self.currentTripModel registerSubscriber:self];
...
}
The following example shows how to cancel registration of the tripModel
callback.
Swift
/*
* MapViewController.swift
*/
deinit {
self.currentTripModel.unregisterSubscriber(self)
}
Objective-C
/*
* MapViewController.m
*/
- (void)dealloc {
[self.currentTripModel unregisterSubscriber:self];
...
}
The following example shows how to implement the GMTCTripModelSubscriber
protocol for handling callbacks when the trip state is updated.
Swift
/*
* MapViewController.swift
*/
func tripModel(_: GMTCTripModel, didUpdate trip: GMTSTrip?, updatedPropertyFields: GMTSTripPropertyFields) {
// Update the UI with the new `trip` data.
self.updateUI(with: trip)
}
func tripModel(_: GMTCTripModel, didUpdate tripStatus: GMTSTripStatus) {
// Handle trip status did change.
}
func tripModel(_: GMTCTripModel, didUpdateActiveRouteRemainingDistance activeRouteRemainingDistance: Int32) {
// Handle remaining distance of active route did update.
}
func tripModel(_: GMTCTripModel, didUpdateActiveRoute activeRoute: [GMTSLatLng]?) {
// Handle trip active route did update.
}
func tripModel(_: GMTCTripModel, didUpdate vehicleLocation: GMTSVehicleLocation?) {
// Handle vehicle location did update.
}
func tripModel(_: GMTCTripModel, didUpdatePickupLocation pickupLocation: GMTSTerminalLocation?) {
// Handle pickup location did update.
}
func tripModel(_: GMTCTripModel, didUpdateDropoffLocation dropoffLocation: GMTSTerminalLocation?) {
// Handle drop off location did update.
}
func tripModel(_: GMTCTripModel, didUpdatePickupETA pickupETA: TimeInterval) {
// Handle the pickup ETA did update.
}
func tripModel(_: GMTCTripModel, didUpdateDropoffETA dropoffETA: TimeInterval) {
// Handle the drop off ETA did update.
}
func tripModel(_: GMTCTripModel, didUpdateRemaining remainingWaypoints: [GMTSTripWaypoint]?) {
// Handle updates to the pickup, dropoff or intermediate destinations of the trip.
}
func tripModel(_: GMTCTripModel, didFailUpdateTripWithError error: Error?) {
// Handle the error.
}
func tripModel(_: GMTCTripModel, didUpdateIntermediateDestinations intermediateDestinations: [GMTSTerminalLocation]?) {
// Handle the intermediate destinations being updated.
}
func tripModel(_: GMTCTripModel, didUpdateActiveRouteTraffic activeRouteTraffic: GMTSTrafficData?) {
// Handle trip active route traffic being updated.
}

}
Error handling
If you subscribed the tripModel and an error occurs, you can get the callback
of tripModel by implementing the delegate method
tripModel(_:didFailUpdateTripWithError:)
. Fleet Engine generated the error
message which follows the Google Cloud Error standard. For the detail error
message definition and all the error codes please refer to
Google Cloud Errors documentation.
Specifically, for trip monitoring, it requires providing a valid authentication
token. 401 UNAUTHENTICATED
will be raised if there is no valid authentication
credentials, like token is expired.403 PERMISSION_DENIED
will be raised if the
caller has no permission to call a specific api (for example, user with consumer
role tries to call updateTrip), or the request has no valid vehicle_id/trip_id
in JWT token.
For more information, see Consumer SDK Error Handling.

Adjusting the camera zoom
The My Location button in the Maps SDK for iOS centers the camera on the device location.
If there is an active Journey Sharing session, you can center the camera to focus on the journey instead of only on the device location.
The Consumer SDK provides an auto camera feature that is enabled by default. The camera zooms to focus on the journey sharing route and the next trip waypoint.
If you require more control of the camera behavior, you can disable or enable
the auto camera feature using the isAllowCameraAutoUpdate
property.
For more camera customizations, see Maps SDK for iOS Moving the camera.
