I did it this way... Basically, remove the "override" keyword from subclass init method, give the property a value from the arguments...

class Enemy { var life: Int = 2 let position: Point

init(x: Int, y: Int) {
    self.position = Point(x: x, y: y)
}

func decreaseLife(by factor: Int) {
    life -= factor
}

}

class SuperEnemy: Enemy { let isSuper: Bool

init(x: Int, y: Int, isSuper: Bool) {
    self.isSuper = isSuper
    super.init(x: x, y: y)
    self.life = 50
}

}

let superEnemy = SuperEnemy(x: 3, y: 2, isSuper: true)
