Errors compiling livevew vers 0.18 usining existing

I’m taking a course by pragamatic studio but it seems the course is already outdated for livevew.

they use liveview 0.16 but I don’t want to go back in versions…so now I get compile errors on App.LiveHelpers that don’t understand…

If I compile their version of the app I get errors as welll…:frowning:

also using the mix creates a schema/table, but I don’t need data access for what I’m working with… kind of confusing
