12,007 PointsI am not sure if I am right but it worked for me (I didn't reach that lvl yet but I did this chalenge just now).
init(withDoors doors: Int, andWheels wheels: Int) {
self.numberOfDoors = doors
self.numberOfWheels = wheels
}
Just have a look at this pice of code. You have created a subclass of Vehicle that means when you create an instance of subclass Car you have to provide the arguments for parameters "withDoors", "andWheels".
So my solution is
class Vehicle {
var numberOfDoors: Int
var numberOfWheels: Int
init(withDoors doors: Int, andWheels wheels: Int) {
self.numberOfDoors = doors
self.numberOfWheels = wheels
}
}
// Enter your code below
class Car: Vehicle {
var numberOfSeats: Int = 4
}
let someCar = Car(withDoors: 4, andWheels: 4)
It works but I am not sure is the right way
