问题
I have created a small application in Unity using Vuforia SDK. It recognizes an image and projects a 3D model on the top of it. I am able to run the app in Unity Editor but getting an issue when I try to create an iOS project and run the app on device.
I am trying to run it on iPhone X (iOS version 11.3) and this is the error that I am getting when the app starts:
VideoBackgroundConfig with screen size of zero received, skipping config step
I searched the issue on net but the solutions that I got didn't work. I am using Vuforia version 7.0.47, Unity version 2017.3.1f1 Personal and XCode version 9.3 beta 4.
Could someone please provide some pointers?

Did you initially create your project on Windows ? And then transfer to OSX ? It is possible that some version of unity or xcode or vuforia don't run on OSX... You should re-import Vuforia after transfering to OSX.
It could also be due to the Lightning parameters, go to Windows>Lightning then Lightmaps tab. Uncheck Auto then rebuild, upload to iOS and try it again.

This video shows how to solve this issue. Basically it is a XCode 9.3 bug. You need to copy an old XCode iOS 11.3 framework folder to the XCode 9.3.
