3,146 PointsIm not sure how to correct the error for this coding challenge
I needed to correct the code for this challenge. I did as much as I could and I can't figure out what I am missing. Im not sure what properties I would add for the "Car" subclass, and when I click preview, it doesn't say I'm missing any.
class Vehicle {
let wheels: Int
let doors: Int
// Designated initializer
init(wheels:Int, doors:Int){
self.wheels = wheels
self.doors = doors
}
}
class Car: Vehicle {
// A car must default to 4 wheels and 4 doors
init(){
super.init(wheels: wheels, doors: doors)// call super.init
}
}

class Vehicle {
let wheels: Int
let doors: Int
// Designated initializer
init(wheels:Int, doors:Int){
self.wheels = wheels
self.doors = doors
}
}
class Car: Vehicle {
// A car must default to 4 wheels and 4 doors
init(){
// call super.init
super.init(wheels:4, doors:4)
}
}
(Basically, you said "use the wheels value for how many wheels the car has" (and same for doors), but never told it what the default value was in the first place)
