I'm testing RealityKit app built by Xcode11 beta2 on Catalina beta2.
I want to publish to App Store Connect for TestFlight internal member.
But "Validate App" apeared popup error dialog. Error is below.
App Store Connect Operation Error
The app references non-public symbols in Payload/appname.app/appname: _$s10RealityKit11LoadRequestCMa, _$s10RealityKit11LoadRequestCyxG7Combine9PublisherAAMc, _$s10RealityKit12AnchorEntityCAA12HasAnchoringAAWP, _$s10RealityKit12AnchorEntityCACycfc, _$s10RealityKit12AnchorEntityCMa, _$s10RealityKit12HasHierarchyPA2A6EntityCRbzrlE6parentAESgvg, _$s10RealityKit12HasHierarchyPA2A6EntityCRbzrlE8addChild_24preservingWorldTransformyAE_SbtF,
...Is this error means that RealityKit is non-public and cannot use TestFlight yet?
I thought apple say that we can test beta app on TestFlight, isn't it?
