Supercharging MVVM With Protocols

Let's apply what we learned in the previous episodes to the week view controller. The week view controller currently configures the cells of its table view. That is something we want to change. The refactoring of the week view controller involves four steps. We create a view model for each table view cell. The WeekViewModel struct generates a view model for each table view cell. We define a protocol to which the view models for the table view cells conform. The WeatherDayTableViewCell class has the ability to configure itself using a view model.
