Swift allows us to redefine specific operators to work in a different way, based on the classes to which we apply them. For example, we can make comparison operators, such as less than (
<) and greater than (
>), and return the results of comparing the
age value when they are applied to instances of
The redefinition of operators to work in a specific way when applied to instances of specific classes is known as operator overloading. Swift allows us to overload operators through the usage of operator functions.
An operator that works in one way when applied to an instance of a class might work differently on instances of another class. We can also redefine the overloaded operators to work on specific ...
