model and view Model - where they are coming from? I haven't found any reference in the project files.Are they built in?

So they should be in UIKit? Or I am missing something. Help is needed! Please. I tried to Google but all links are about MVC.

"Model" and "View Model" aren't components of UIKit, rather, they're terms used in object-oriented programming to describe a kind of class or type. In this project, CurrentWeather is our model, and in this video Pasan builds a class called CurrentWeatherViewModel which takes an instance of CurrentWeather.

A 'model' is a very typical usage of a class. A Person, Car, Movie, or Book would all be examples of models. They describe what an object is, and what sorts of properties it has. A 'view model' tells our app how it should display the data we have.
