Design Pattern: Model-View-ViewModel (MVVM)

is a structural design pattern that separates objects into three distinct groups:

• Models

  • hold application data. They’re usually structs or simple classes.

• Views

  • display visual elements and controls on the screen. They’re typically subclasses of UIView.

• View models

  • transform model information into values that can be displayed on a view. They’re usually classes, so they can be passed around as references.
