After you enable billing and create an API key, you're ready to set up the Xcode project that you use to develop your app.
Release notes are available for each release.
Step 1: Install the required software
To build a project using the Maps SDK for iOS, you must download and install:
Step 2: Create the Xcode project and install the Maps SDK for iOS
To install the API in a new project, follow these steps:
Use CocoaPods
The Maps SDK for iOS is available as a CocoaPods pod. CocoaPods is an open source dependency manager for Swift and Objective-C Cocoa projects.
If you don't already have the CocoaPods tool, install it on macOS by running the following command from the terminal. For details, see the CocoaPods Getting Started guide.
sudo gem install cocoapods
Create a Podfile
for the Maps SDK for iOS and use
it to install the API and its dependencies:
- 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.
- Select the iOS > App template.
- On the project options screen:
- Enter the Project Name.
- Record the value of the Bundle identifier field. You can use that value to restrict your API key below.
- Set the project Interface to Storyboard.
- Set the Language to Swift or Objective-C.
- Create a file named
Podfile
in your project directory. This file defines your project's dependencies. - Edit the
Podfile
and add your dependencies along with their versions. Here is an example which includes the dependency you need for the Maps SDK for iOS:source 'https://github.com/CocoaPods/Specs.git' platform :ios, '14.0' target 'YOUR_APPLICATION_TARGET_NAME_HERE' do pod 'GoogleMaps', '8.3.0' end
Make sure to regularly runpod outdated
to detect when there is a newer version to ensure you're always on the latest. If necessary, upgrade to the latest version. - 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 thePodfile
, 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.
To update the API for an existing project, follow these steps:
- Open a terminal and go to the project directory containing the
Podfile
. - Run the
pod update
command. This will update all of the APIs specified in thePodfile
to the latest version.
Install manually
This guide shows how to manually add the XCFrameworks containing the Maps SDK for iOS to your project and configure your build settings in Xcode. An XCFramework is a binary package that you can use on multiple platforms, including machines using Apple silicon.- Download the following SDK binaries and resource files:
- Unpack the zipped files to access the XCFrameworks and resources.
- 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.
- Select the iOS > App template.
- On the project options screen:
- Enter the Project Name.
- Record the value of the Bundle identifier field. You can use that value to restrict your API key below.
- Set the project Interface to Storyboard.
- Set the Language to Swift or Objective-C.
- Drag the following XCFrameworks into your project under
Frameworks, Libraries, and Embedded Content. Make sure
to select Do Not Embed for each XCFramework:
GoogleMaps.xcframework
GoogleMapsBase.xcframework
GoogleMapsCore.xcframework
- (Premium Plan customers only)
GoogleMapsM4B.xcframework
- Drag
GoogleMaps.bundle
from GoogleMapsResources you downloaded into the top level directory of your Xcode project. When prompted, ensure Copy items if needed is selected. - Select your project from the Project Navigator, and choose your application's target.
- Open the Build Phases tab for your application's target,
and within Link Binary with Libraries, and add the following
frameworks and libraries:
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
. If these settings are not visible, change the filter in the Build Settings bar from Basic to All.To install the Places SDK for iOS XCFramework, see Get Started with the Places SDK for iOS.
Step 3: Add your API key to the project
In Get an API key, you generated an API key for your app. Now add that key to your Xcode project.
In the following examples, replace YOUR_API_KEY
with your API key.
for more information.
Swift
Add your API key to your AppDelegate.swift
as follows:
- Add the following import statement:
import GoogleMaps
- Add the following to your
application(_:didFinishLaunchingWithOptions:)
method, using your API key:GMSServices.provideAPIKey("YOUR_API_KEY")
- 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:
- Add the following import statement:
@import GoogleMaps;
- Add the following to your
application:didFinishLaunchingWithOptions:
method, using your API key:[GMSServices provideAPIKey:@"YOUR_API_KEY"];
- If you are also using the Places API, add your key again as shown here:
[GMSPlacesClient provideAPIKey:@"YOUR_API_KEY"];
Step 4: Add a map

GMSMarker *marker = [[GMSMarker alloc] init]; marker.position = CLLocationCoordinate2DMake(-33.86, 151.20); marker.title = @"Sydney"; marker.snippet = @"Australia"; marker.map = mapView; } @end
Step 5 (Optional): Declare the URL schemes used by the API
Beginning with iOS 9 and Xcode 7, apps can declare the URL schemes that they
intend to open, by specifying the schemes in the app's Info.plist
file. The
Maps SDK for iOS opens the Google Maps mobile app when the user clicks
the Google logo on the map, and your app can therefore declare the relevant URL
schemes.
To declare the URL schemes used by the Maps SDK for iOS, add the
following lines to your Info.plist
:
The following screenshot shows the configuration in the Xcode user interface:
Without the above declaration, the following errors can occur when the user taps the Google logo on the map:
-canOpenURL: failed for URL: "comgooglemaps://" - error: "This app is not allowed to query for scheme comgooglemaps" -canOpenURL: failed for URL: "googlechromes://" - error: "This app is not allowed to query for scheme googlechromes"
To eliminate these errors, add the declaration to your Info.plist
.
What's next
Now that you have an API key and an Xcode project, you can create and run apps. The Maps SDK for iOS provides many tutorials and sample apps that can help you get started. For more details, see:
