✅ Mock class doesn't exist after moving files around even though it does

I moved some files into a view folder and now it can't find a mock class I have in the View-Controller. It even sees the prediction for the class yet it doesn't see it still. I've closed VS, I've cleaned and rebuilt the solution etc. Idk what else to do/try.
