Prepare for iOS 14+

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

Prerequisites

• Interactive Media Ads SDK 3.12.1 or higher.

Enable SKAdNetwork to track conversions

The Interactive Media Ads SDK supports conversion tracking using Apple's SKAdNetwork, which means Google is able to attribute an app install even when IDFA is unavailable.

To enable this functionality, you will need to update the SKAdNetworkItems key with an additional dictionary in your Info.plist.

<key>SKAdNetworkItems</key>
  <array>
    <dict>
      <key>SKAdNetworkIdentifier</key>
      <string>cstr6suwn9.skadnetwork</string>
    </dict>
  </array>

Request App Tracking Transparency authorization

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. Below 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 as part of the App Tracking Transparency dialog, as shown below:

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 Interactive Media Ads SDK can use the IDFA in ad requests.

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

#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.

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.
