cant get super int

im having a major brain stump here and cant get the super int to work

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
    }
}

I know the feeling. I come from Java, and super works fine there by itself. But here you need super.init() and also the labels:

class Car: Vehicle {
    // A car must default to 4 wheels and 4 doors
    init(){
      // call super.init
      super.init(wheels: 4, doors: 4)
    }
}
