Hi we have similar issue with our VisionOS build using Unity, and XCode 15 beta 8
App Store Connect
Dear Developer,
We identified one or more issues with a recent delivery for your app, "Skatrix Vision demo" 0.1 (6). Please correct the following issues, then upload again.
ITMS-90338: Non-public API usage - The app references non-public symbols in Frameworks/UnityFramework.framework/UnityFramework: _ar_skeleton_get_skeleton_root_transform_for_joint. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed.
we can't remove this code because it's inside Unity package and it's needed to build the app, please let us know how can we fix that
