Hi,
we have developed an app using ARKit & UE 4.19, successfully built it for distribution.
Then we sent it to the App Store, but Apple rejected it because of usage of TrueDepth API with no purpose.
In this thread App rejected because of TrueDepth APIs - Mobile - Unreal Engine Forums it is recomended to turn off ARKit plugin. Obviously it’s not a solution for us because ARKit is the main feature.
Conversation with the review team gave us none. They says that we need to remove TrueDepth API if it’s not used in our app.
Is it used in the engine and maybe someone can help us with the right explanation for the review team?
We are using ARKit for AR architecture visualization (only backside camera) with stadart engine ARKit realization.
Our app is developed for [YIT Group (Russia)][1].
We’ve already released Vuforia-based version for Android. Here is the link on Play Market:

And here is an iOS device realtime footage:

Hi,
the problem is that we are using Unreal Engine (non source code version) and we have no ability to remove the TrueDepth API by ourselfs without forking the whole engine! Is there any other possible way to pass the review? We can't wait a few months till Epic Games releases a new version of the engine. We've already waited for the 4.19 version for about a month.
Best regards,
Roman Kalinin

Hello,
our app is built with Unreal Engine 4 (4.19 version) and the main feature in our app is an AR visualization using ARKit reality system built in the engine by Epic Games.
We are using only backside camera for scanning geometry and placing 3D models in the real space. We are not collecting any information and not sharing data to any third parties.
As far as we can see in Unreal Editor and its AR realization, Epic Games are aiming to use front side camera in future releases, but right now it's disabled, so no information should be collected, too.
In our app we are using internet connection to download news from our server and send call requests by users to it. But no data from TrueDepth API is sending from the app.

During review, we found that your app includes TrueDepth APIs. However, we were not able to locate any features in your app that use TrueDepth APIs.
Next Steps
If your app does not include any features that use TrueDepth APIs, please remove them from your app.
As your app uses the Unity ARKit plugin, it would be appropriate to update to the latest version, which includes a setting that allows you to exclude TrueDepth APIs.
If your app does include features that use TrueDepth APIs, please reply to this message in Resolution Center to provide information on how to locate them.
