He complementado este curso con la lectura de algunos libros, entre ellos tengo este: Sumergete en los patrones de diseño
Me ha ayudado a entender la POO

Creo que la programación orientada a protocolos (POP) es la mejor opción a OOP.

Busque como, desde el hijo, sobrescribir una var que proviene del padre y descubrí override

class Vehicle {
    var currentSpeed = 0.0
    var typeOfVehicle = ""
    var color = ""
    var description: String {
        return "Your \(typeOfVehicle):"
    }
    func makeNoise(){
        // empty
        print("El ruido depende del vehículo")
    }
}

class Car : Vehicle {
    var band: String
    var version: String
