DCR Video iOS14 Migration

Engineering Portal Digital US DCR & DTVR DCR Video iOS14 Migration

Overview

Apple recently released a new policy on consent requirements for its mobile advertising tool, Identifier for Advertisers (IDFA). With this new policy, (App Tracking Setting) users can choose whether an IDFA may be used by mobile applications. iOS 14 was released on Sept 16th.

What does this mean for measurement?

Apple added a new Framework called “The App Tracking Transparency Framework”. This is now required to control whether the Ad Framework will return the IDFA. If our app requests the IDFA, but advertisingTrackingEnabled=No, then we will get: IDFA = 00000000 -0000-0000-0000-000000000000. If a client is using our APP SDK v7 and below, running on a device with iOS14 installed, as this is a new framework, our SDK will never be able to retrieve the IDFA.

Version 8 of our App SDK will come in two versions. One that is enabled to work with the App Tracking Transparency Framework, and another version that does not use the Ad Framework. A Table outlining the various iOS versions and Nielsen AppSDK versions is located later in this document.

Transparency Framework

Apple was going to force all publishers to check if ATTrackingManager. AuthorizationStatus was equal to authorized. Now however, since they are not forcing publishers to ask the user, as long as the ATTrackingManager.AuthorizationStatus is equal to undefined, or authorized, you are allowed to grab the IDFA value. The change they made was to allow us to use undefined as a valid state. 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.
