iOS Object-Oriented Swift Class Inheritance Inheritance

Increment life instead of creating a class

Instead of Declaring new class can't we just define a new function which would increment life of enemy as if the enemy is declared as variable and not a constant so it can be changed....& If this can't be done can anyone justify me why????????????

You can totally do that. I don't think this was the best way to describe inheritance, but it works I guess. If we increment life, the programmer would have to do so every time he/she creates an instance of that class. It is just cleaner and less work in the long run to use inheritance.
