1,474 PointsI think online compiler is broken: create a subclass of Vehicle, named Car, that adds an additional stored property
https://teamtreehouse.com/library/objectoriented-swift-2/class-inheritance/creating-a-subclass
class Vehicle { var numberOfDoors: Int var numberOfWheels: Int
init(withDoors doors: Int, andWheels wheels: Int) {
self.numberOfDoors = doors
self.numberOfWheels = wheels
}
}
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: 4, andWheels: 4)
Works perfectly fine in Playgrounds
class Vehicle {
var numberOfDoors: Int
var numberOfWheels: Int
init(withDoors doors: Int, andWheels wheels: Int) {
self.numberOfDoors = doors
self.numberOfWheels = wheels
}
}
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: 4, andWheels: 4)

class Car : Vehicle {
// Subject asks for a default value = 4, I think it's easier to store it in a variable
var numberOfSeats : Int = 4
}
// Enter your code below
let someCar = Car(withDoors : 4, andWheels: 4)
// Here you can
print(someCar.numberOfSeats)
// prints 4
