[iOS13][UaaL] Scene does not load when using Unity as a Library

iOS

-

Reproduction steps:
1. Extract "NewXCode.zip (60.9 KB)" and open the folder
2. Open and build for iOS the project in "UnityProject.zip (247.1 KB)"
3. Create a new Xcode Workspace
4. Import NewXCode.xcodeproj (the root of NewXCode you extracted) to the Xcode Workspace
5. Import Unity-iPhone.xcodeproj of the project you built to the Xcode Workspace

All Remaining steps are done in Xcode Workspace

6. Under Unity-iPhone select "Data" and check Target Membership "UnityFramework"
7. Under Unity-iPhone select Libraries -> Plugins -> iOS -> NativeCallProxy.h
8. Set UnityFramework Target Membership visibility to Public
9. Deploy NewXCode target to iOS

Expected result: the project launches successfully
Actual result: project starts launching but the screen stays white/black indefinitely

10. This can be resolved by replacing "<root of the Project from step 2>/Classes/UnityAppController.mm" with the one attached in edits
