Unable To Find Barracuda Namespace Within Editor/vs Code On Macos

I’m working with Unity 2018.3.12f1 on MacOS 1.13.

Barracuda.Core is in my Assets folder, but I receive these errors in the Console and cannot load:

Everything loads properly with the same project set up in Windows.

Maybe your project is set earlier than 4.x version of .NET?

Try:
import Unity.Barracuda
