Overriding superclass issues

Not entirely sure what I am missing or miscoding in this challenge task. The task reads: In the editor, I have provided a class named Vehicle.

Your task is to create a subclass of Vehicle, named Car, that adds an additional stored property numberOfSeats of type Int with a default value of 4.

Once you've implemented the Car class, create an instance and assign it to a constant named someCar.

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 

    override init(withDoors doors: Int, andWheels wheels: Int, andSeats seats: Int) {
        super.init(withDoors: doors, andWheels: wheels, andSeats: seats)
        self.numberOfSeats = seats

let someCar = Car(withDoors: 4, andWheels: 4, andSeats: 4)
