What I'm I missing

Should I declare numberOfSeats outside of init or inside???

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

let somecar = Car.init(withDoors: 2, andWheels: 5)

Suraz - The problem is when you are creating an instance

The constant should be someCar not somecar as you have it. Also you do not need .init when you create an instance

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