What is a class?
In object-oriented programming, a class is an extensible
program-code-template for creating objects, providing initial
values for state (member variables) and implementations of
behavior (member functions or methods).

We can define a class in Swift using the class keyword. We instantiate
a new instance of a class using the class name followed by (). Classes
can have properties and functions associated with them.
A property is a value that is associated with an instance of a class
and a method is a function that is associated with a class. A class is
a way of grouping related data along with the methods that
operate on them.
