Compile Error

I cannot compile the code

Vehicle.swift 
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: wheels, doors: doors)
    }
}

You're close! super.init needs you to specify the amount of wheels and doors. The amounts that you need are in one of the comments that the objective supplies, fortunately.

If you're still stuck:

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)
    }
}

Hope this helps!

I was initializing it in init(). Well, thanks a lot.
