Sin meterme en detalles de arrays solo agregue la variable pero a la clase Debit donde modifique el init.

class Transaction {
    var value: Float

        self.value = value

Pensando en que categoría es un catálogo, la agrego como una clase, con el fin de tener un control sobre estas. Aunque debería ser un Array, Enum o algo por el estilo ya que aun no existe una BD :D

Reto:

class Transaction {
    var value: Float
    var name: String
    var category: String
    
    init(value: Float, name: String, category: String) {
        self.value = value
        self.name = name
        self.category = category
    }
}

Las transacciones quedan asi:

me.account?.addTransaction(transaction:
    Debit(value: 20, name: "Cafe con friends", category: "Hobbies"))

me.account?.addTransaction(transaction:
    Debit(value: 100, name: "Juego PS4r", category: "Regalos"))

me.account?.addTransaction(transaction:
    Debit(value: 500, name: "PS4", category: "Regalos"))

me.account?.addTransaction(transaction:
    Gain(value: 1000, name: "Salario", category: "Trabajo"))

Me surgió la duda de por qué las clases hijas no requieren inicilizadores. ¿Es porque no tienen atributos? o ¿Es porque heredan los inicializadores de Transaction?

Diego Forero

Team Platzi•

Como las clases hijas heredan de su clase padre no necesitan inicializar valores a menos que tenga atributos nuevos, en este caso se debe sobreescribir el inicializador y agregar el atributo nuevo.
