There is a known issue when using:
- Vuforia 7
- Xcode 9.3
- Devices running iOS 11.3 beta && support ARKit (version 1.5, bundled with iOS 11.3 beta)
When developing with these versions, you may observe a camera preview that renders a black screen.
This is being addressed in an upcoming release of Vuforia. In the meantime, it is recommended to use Xcode 9.2 (or earlier) to ensure development continuity.
We will provide an update once the issue has been resolved.
Thanks for your continued interest in Vuforia,
