In practice, you don’t need to write self in your code very often. If
you don’t explicitly write self, Swift assumes that you are referring
to a property or method of the current instance whenever you use a
known property or method name within a method.
The main exception to this rule occurs when a parameter name for an
instance method has the same name as a property of that instance. In
this situation, the parameter name takes precedence, and it becomes
necessary to refer to the property in a more qualified way. You use
the self property to distinguish between the parameter name and the
property name.
