I don't see how we arrived at super.init

I don't see how we arrived at super.init. To me it seems that 'super' is a arbitrary variable.

class SuperEnemy: Enemy { // Inheritance - giving a class the properties of another class. let isSuper: Bool = true

/////////////////////////////////// Override Init ///////////////////////////////////

override init(x: Int, y: Int) {  // overiding the initializer of the superclass w/ own.
    super.init(x: 4, y: 3)

Hi Von,

It sort of is arbitrary but it's also a common convention in Object-Oriented Programming. super is a convenient reference to a given class's parent-class. You need to call the init method of your parent-class in your child-class in order to inherit the parent-class's data and methods. That's how inheritance works.
