iOS Object-Oriented Swift 2.0 Class Inheritance Creating a Subclass

What's wrong with my code? I'm stuck at the exercise for creating a subclass, and I can't seem to get it right.

I don't understand what goes inside the brackets for the init part of an inherited / override init.

Also, not sure what is wrong with the instance I'm trying to create.

classes.swift
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

    override init(withDoors doors: Int, andWheels wheels: Int) {

            Car.init(withDoors: Int, andWheels: Int) {

    self.numberOfSeats = 4

    }
        }
           }
    let someCar = Car(withDoors: 4, andWheels: 4)

You have too many closing braces, the assignment to numberOfSeats should come before the super class initializer call, and instead of Car.init, its super.init

class Car: Vehicle { 
    var numberOfSeats: Int

    override init(withDoors doors: Int, andWheels wheels: Int) {
            self.numberOfSeats = 4
            super.init(withDoors: doors, andWheels: wheels)
    }
 }
let someCar = Car(withDoors: 4, andWheels: 4)

Thank you so much!! I get it now.
