Vuforia Stripping Assemblies

Reproduced on a few versions of Unity 2019.3 on Windows and MacOS. I cannot get vuforia to build on 2019.3.

- Starting with a blank 3d project.
- Enable "Vuforia Augmented Reality Supported" on the Player (iOS).
- Try to build iOS
- I've consistently gotten the below result
- Disable Vuforia AR Support: Builds just fine

I've also tried targeting .net 4 and 2, neither changes the results.

Same problem. Android build works fine!

 

This was confirmed to be a bug in some versions... I think alpha 10 through beta 1 (so far, it hasn't been fixed yet, could be present in beta 2 when that's released.) I ended up using alpha 6 to build and it works for me
