Anyone have something that works for the Final Challenge?

I'm running into walls here.

Vehicle.swift 
class Vehicle {
    var wheels: Int
    var 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(wheels: Int=4, doors: Int=4){
        // call super.init
        super.init(wheels: wheels, doors: doors)
    }
}
