Prepare for iOS 14+

This guide outlines the changes needed to prepare your app for iOS 14.

Key Point: Google Mobile Ads SDK version 8.3.0 or higher includes all the features discussed in this guide. Keep your app up-to-date with the latest SDK version to ensure it fully supports iOS 14.

Enable SKAdNetwork to track conversions

Prerequisites: Google Mobile Ads SDK 7.64.0 or higher

The Google Mobile Ads SDK supports conversion tracking using Apple's SKAdNetwork, which lets Google and participating third-party buyers attribute an app install even when the IDFA is not available.

To enable this functionality, update the SKAdNetworkItems key with an additional dictionary that defines Google and participating third-party buyers' SKAdNetworkIdentifier values in your Info.plist.

The snippet below includes Google (cstr6suwn9.skadnetwork) and select additional buyer SKAdNetwork identifiers who have provided these values to Google. Google is committed to updating this list to include additional buyers and to working with the industry on solutions to share SKAdNetworkIdentifier values more broadly. Please check this page for updates.

Mediation

If you use mediation, check each ad network partner's documentation for any additional SKAdNetworkIdentifier values that they require:

• AdColony
• AppLovin (requires sign-in)
• Chartboost
• Facebook
• Fyber
• i-mobile
• InMobi
• ironSource
• maio
• MoPub
• myTarget
• nend
• Tapjoy
• Unity Ads
• Vungle

For ad sources that are not listed here, reach out to your account team to find SKAdNetworkIdentifier values that they require.

Request App Tracking Transparency authorization

Prerequisites: Google Mobile Ads SDK 7.64.0 or higher

Key Point: If you decide to include App Tracking Transparency (ATT) in your app, you can use the User Messaging Platform (UMP) SDK to trigger an IDFA explainer that gives users some context of why you're asking for this permission. Be aware that the usage of the UMP SDK affects all users of your app.

If you're not using the UMP SDK, the rest of this page shows you how to implement the OS-level ATT authorization request manually.

To display the App Tracking Transparency authorization request for accessing the IDFA, update your Info.plist to add the NSUserTrackingUsageDescription key with a custom message describing your usage. Here is an example description text:

<key>NSUserTrackingUsageDescription</key>
<string>This identifier will be used to deliver personalized ads to you.</string>

The usage description appears in the App Tracking Transparency dialog box:

To present the authorization request, call requestTrackingAuthorizationWithCompletionHandler:. We recommend waiting for the completion callback prior to loading ads so that if the user grants the App Tracking Transparency permission, the Google Mobile Ads SDK can use the IDFA in ad requests.

Swift

import AppTrackingTransparency
import AdSupport
...
func requestIDFA() {
  ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
    // Tracking authorization completed. Start loading ads here.
    // loadAd()
  })
}

Objective-C

#import <AppTrackingTransparency/AppTrackingTransparency.h>
#import <AdSupport/AdSupport.h>
...
- (void)requestIDFA {
  [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
    // Tracking authorization completed. Start loading ads here.
    // [self loadAd];
  }];
}

For more information about the possible status values, see ATTrackingManager.AuthorizationStatus.

Key Point: For a better user experience, we recommend adding an explainer preceding the call to requestTrackingAuthorizationWithCompletionHandler: to clarify the permission and data usage to users.

Same app key

Prerequisites: Google Mobile Ads SDK 8.3.0 or higher

The Google Mobile Ads SDK introduces the same app key to help you deliver more relevant and personalized ads by using data collected from the app the user is using. See the global settings guide for more information on how to implement the same app key.

SKOverlay

Prerequisites: Google Mobile Ads SDK 8.5.0 or higher

A new API for recommending another app or an App Clip's corresponding full app was added in iOS 14: SKOverlay

SKOverlay presents a recommended app as an overlay on top of an ad, so users can install it without leaving your app.

If you use the Google Mobile Ads SDK version 8.5.0 or higher, you do not need to take any action to enable SKOverlay for your app. When there is a positive performance benefit for users and advertisers, ads are automatically enhanced with SKOverlay.

Disclose data usage in the App Store

Apple requires that developers publishing apps on the App Store disclose certain information regarding their apps' data use. Apple has announced that these disclosures will be required for new apps and app updates starting December 8, 2020.

Learn more about the data disclosure requirements.

App-Bound Domains

In June 2020, Apple introduced App-Bound Domains as an opt-in feature for developers to limit the domains for all WKWebView in an app to 10 or fewer, through the WKAppBoundDomains Info.plist key.

Currently, the Google Mobile Ads SDK doesn't support this feature.

If you add the WKAppBoundDomains key to your Info.plist file, the Google Mobile Ads SDK may fail to load ads.
