Setup and Demo

Use CocoaPods

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, '10.0'
   
   target 'YOUR_APPLICATION_TARGET_NAME_HERE' do
     use_frameworks!
     pod 'GoogleMaps', '4.0.0'
     pod 'Google-Maps-iOS-Utils', '3.4.0'
   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.

Use Carthage

1. Install Carthage. There are several methods, so see the Carthage README file for exact steps.
2. If you don't have an Xcode project yet, create one now and save it to your local machine. (If you're newer to iOS development, create a new project and select the iOS App template. In Xcode 11.7 or earlier, create a Single View Application.)
3. Create a file named Cartfile in your project directory. This file defines your project's dependencies.
4. Edit the Cartfile and add the Maps SDK for iOS Utility Library dependency:
   

   github "googlemaps/google-maps-ios-utils"

5. Save the Cartfile.
6. In a terminal window, go to the directory containing the Cartfile:
   

   cd <path-to-project>

7. Run the update command:
   

   carthage update --platform iOS

   
   This will install the APIs specified in the Cartfile, along with any dependencies they may have.
8. In the Finder, in your project directory, go to the downloaded framework files under Carthage/Build/iOS.
9. Add the Maps SDK for iOS frameworks into your project by dragging the following bundles into your project. (When prompted, select Copy items if needed, please use the same version as above.)
   • GoogleMaps-x.x.x/Base/Frameworks/GoogleMapsBase.framework
   • GoogleMaps-x.x.x/Maps/Frameworks/GoogleMaps.framework
   • GoogleMaps-x.x.x/Maps/Frameworks/GoogleMapsCore.framework
   • GoogleMaps-x.x.x/Maps/Frameworks/GoogleMapsUtils.framework
   Premium Plan customers must also include GoogleMaps-x.x.x/M4B/Frameworks/GoogleMapsM4B.framework.
10. Right-click GoogleMaps.framework in your project, and select Show In Finder.
11. Drag the Carthage/Build/iOS/GoogleMaps.framework/Resources/GoogleMaps.bundle from the Resources folder into your project. When prompted, ensure Copy items into destination group's folder is not selected.
12. Select your project from the Project Navigator, and choose your application's target.
13. Open the Build Phases tab for your application’s target, and within Link Binary with Libraries, add the following frameworks:
    • Accelerate.framework
    • CoreData.framework
    • CoreGraphics.framework
    • CoreImage.framework
    • CoreLocation.framework
    • CoreTelephony.framework
    • CoreText.framework
    • GLKit.framework
    • ImageIO.framework
    • libc++.tbd
    • libz.tbd
    • OpenGLES.framework
    • QuartzCore.framework
    • SystemConfiguration.framework
    • UIKit.framework

14. Choose your project, rather than a specific target, and open the Build Settings tab. In the Other Linker Flags section, add -ObjC. If these settings are not visible, change the filter in the Build Settings bar from Basic to All.

Use Swift Package Manager

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 Exact from the dropdown list, enter the latest version of the Maps SDK for iOS Utility Library (e.g. "3.4.0") and select Next.

Swift

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

1. Add the following import statement:

   import GoogleMaps

2. Add the following to your application(_:didFinishLaunchingWithOptions:) method, replacing YOUR_API_KEY with your API key:

   GMSServices.provideAPIKey("YOUR_API_KEY")

3. If you are also using the Places API, add your key again as shown here:

   GMSPlacesClient.provideAPIKey("YOUR_API_KEY")

Objective-C

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

1. Add the following import statement:

   @import GoogleMaps;

2. Add the following to your application:didFinishLaunchingWithOptions: method, replacing YOUR_API_KEY with your API key:

   [GMSServices provideAPIKey:@"YOUR_API_KEY"];

3. If you are also using the Places API, add your key again as shown here:

   [GMSPlacesClient provideAPIKey:@"YOUR_API_KEY"];
