iOS Object-Oriented Swift Class Inheritance Creating a Subclass

No error, error

In the editor, I have provided a class named Vehicle.

Your task is to create a subclass of Vehicle, named Car, that adds an additional stored property numberOfSeats of type Int with a default value of 4.

Once you've implemented the Car class, create an instance and assign it to a constant named someCar.

It says that my code can't be compiled but when I view Preview there are no compiler errors.

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{
  var numberOfSeats: Int = 4
}

let someCar = car(withDoors: 5, andWheels: 5)

The "code cannot be compiled" message here seems like a bad error message to me, because Swift handles it just fine on my machine. I think the main thing that went wrong here is that the challenge asked for a class named Car, but the one you made is named car (be sure to pay attention to capitalization! It matters in Swift). If you fix that, I think you'll be good

cool thank you so much!

Please provide a best answer for Michael :)
