Missing parameter for "andWheels" even though I put a parameter... help?
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 = Vehicle(withDoors: 2, andWheels: 4, Car(numberOfSeats: 4))

class Car: Vehicle {

}
let someCar = Car(withDoors: 4, andWheels: 4)
You have:
let someCar = Vehicle(withDoors: 2, andWheels: 4, Car(numberOfSeats: 4))
First, you were supposed to make someCar a Car, not a Vehicle. Second, you can't pass a 3rd parameter, because the init inherited from Vehicle only accepts two parameters: withDoors and andWheels. Third, you don't need to pass in the number of seats because the number is hardcoded in the Car class.
