Prepare for iOS 14+

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

Prerequisites

• PAL SDK 2.2.2 or higher.

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. 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 PAL 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.
