This page describes how to set up the utility library for the Maps SDK for iOS.

To try these utilities, you can either:

• Install the utility library's into an existing Xcode project. Add these utilities in your own project.
• Install and run the demo app. The demo app is a standalone project that contains all of the code required to try out the utilities.

Follow these steps to add the utility library to your Xcode workspace:

1. If you don't have an Xcode project yet, create one now and save it to your local machine. (If you're new to iOS development, create a new project and select the iOS App template. On Xcode 11.7 or older, create a Single View Application.)
2. Add the Maps SDK for iOS as a dependency. See Installing the SDK for options.
3. In your Xcode project, navigate to File -> Swift Packages -> Add Package Dependency.
4. In the presented window, enter the Maps SDK for iOS Utility Library repository URL https://github.com/googlemaps/google-maps-ios-utils and select Next.
• At this point, you may be prompted to authenticate with your GitHub account. Follow the instructions to create a GitHub personal access token to continue the process.
5. In the next window, select the Version radio option, select Up to Next Major Version from the drop-down list, and enter the latest version of the Maps SDK for iOS Utility Library (for example, "6.0.0").
6. Click the drop-down next to Add to Project, select your project, and select Add Package.

1. If you don't have an Xcode project yet, create one now and save it to your local machine. (If you're new to iOS development, create a Single View Application.)
2. If you don't already have a pod file for your project, create a file named Podfile in your project directory. This file defines your project's dependencies.
3. Edit your project's pod file and add a dependency on the Google-Maps-iOS-Utils pod. Here is an example which includes the dependencies you need for the Maps SDK for iOS and the utility library:

   source 'https://github.com/CocoaPods/Specs.git'
   platform :ios, '16.0'
   
   target 'YOUR_APPLICATION_TARGET_NAME_HERE' do
     use_frameworks!
     pod 'GoogleMaps', '10.0.0'
     pod 'Google-Maps-iOS-Utils', '6.1.2' # x-release-please-version
   end

4. Run pod install.
5. 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.

Note: The marker clustering utility is dependent on the quadtree, but you can use the quadtree without marker clustering. If you want only the quadtree utility, you can change pod 'Google-Maps-iOS-Utils' to 'Google-Maps-iOS-Utils/QuadTree' in your pod file.

See

for instructions on generating an API key and adding it to your Xcode project.

After you add the API key, build and run the project.

See the documentation on each utility for more information on using it in your app:

• Marker clustering
• Quadtree
• KML rendering
• GeoJSON rendering
• Heatmap

The utility library includes a demo app that you can install and then try out each utility.

Install the demo app:

1. Download the code sample archive from GitHub and unpack the archive.
2. Open a terminal window, navigate to the directory where you expanded the sample files, and drill down into the appropriate samples directory for the language you want to use:
   • For Swift, run cd google-maps-ios-utils-master/samples/SwiftDemoApp
   • For Objective-C, run cd google-maps-ios-utils-master/samples/ObjCDemoApp
3. Run the following command:
   

   pod install

4. 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.

In

, you generate an API key for your app. Now add that key to the Xcode project for the demo app.

Add your API key to your AppDelegate.swift as follows:

1. Add the following import statement:

   import GoogleMaps

2. Edit the following line to add your API key between the double quotes:

   // Change this key to a valid key registered with the demo app bundle id.
   let mapsAPIKey = ""

Add your API key to your AppDelegate.m as follows:

1. Add the following import statement:

   @import GoogleMaps;

2. Edit the following line to add your API key between the double quotes:

   // Change this key to a valid key registered with the demo app bundle id.
   static NSString *const kMapsAPIKey = @"";

After you add the API key, build and run the project:

• If you are running the Swift version of the demo, you can select which utility to view in the app.
• If you are running the Objective-C version of the demo, you see the demo of the marker clustering utility. You can then edit the Objective-C version of the demo to try each utility. See the Add a utility to your app section below for more information.
