Google Mobile Ads Unity Plugin - iOS App Tracking Transparency

[Kwong]

Hi I'm using Google Mobile Ads Unity Plugin v5.4.0, but it does not have NSUserTrackingUsageDescription included in info.plist after building iOS Xcode project. Is this included in the latest v5.4.0 GMA Unity plugin?

Hi Kwong,

Thank you for reaching out to us.

As per documentation, the latest v5.4.0 GAM unity plugin only included the SKAdNetwork identifiers that will automatically included in Info.plist. In preparing for iOS 14+, you needed to update your Info.plist to add the NSUserTrackingUsageDescription key with a custom message describing your usage.

Hi,

I could add that manually in xcode project, but that would lead to these issues:

1. I have to manually add that key in info.plist everytime I build xcode project from Unity. This is counter productivity and likely to be error prone when we miss/forget adding the key after each build 
2. Does Google Mobile Ads For Unity call requestTrackingAuthorization automatically after we add the NSUserTrackingUsageDescription? Or do we have to implement our own native code for Android and iOS and then link them to Unity C#?

Look forward to hear from you on these issues.

Hi Kwong,

Thank you for responding back to us. I work along with Princess and will be helping you today. Having looked over the previous comments. I would like to reiterate what was said previously. If you follow what is being shown here . This will help to resolve the questions that you have asked. As for having to redo this every build? You would not. As for if this is built in? Yes, once you do as is suggested it should work as it states. The ATT system is only for iOS and will only take affect for the iOS devices. Does not need to be coded natively.

Hi William,

The link you sent is for native iOS implementation, but not for Unity C#. However, here are the steps I did:

1. Build iOS project from Unity 3D.

2. Open the iOS project in Xcode

3. Add "Privacy - Tracking Usage Description" in Info.plist

4. Add "AppTrackingTransparency.framework" under Unity-iPhone.xcodeproj -> General -> Frameworks,Libraries,and Embedded Content

There's no popup asking for tracking permission until I added "requestTrackingAuthorizationWithCompletionHandler" in iOS native code in Xcode project. This seems to be not out of box and we need to always update native iOS code to enable the tracking popup after building a clean Xcode project from Unity 3D.

Also, there are many times we need to build a clean Xcode project from Unity 3D Editor because the Unity messes up the existing project by adding duplicate libraries and run scripts sometime or we need to build from different machines. In that case, we always need to add those iOS native code to the Xcode project, which is a bit counter productive

Let me know if I missed any step. Thanks and look forward to your reply.

Hi Kwong,

The NSUserTrackingUsageDescription is on the Unity platform side, and not on the SDK level. With this, we recommend to follow the Post build steps guide on this link instead: https://alanyeats.com/post/unityapptrackingtransparencypopup/

Thanks Teejay. I noticed Unity has released a plugin to show the iOS Ad Tracking Transparency popup. Does GMA handle the ad tracking automatically once user allow tracking? Is there any extra step we need to setup for GMA unity plugin side?
