SwiftUI Decorator Pattern

Swift decorator pattern explained in real MVVM SwiftUI project simulating a food store with different main foods and extra flavours to add or remove easily without changing the core object.

How decorating works

let pizza:Order = Pizza()
print(pizza.cost()) --> //3.20

Decorating pizza with mushroom

let mushroomPizza:Order = MushroomAdditionDecotator(pizza)
print(mushroomPizza.cost()) --> //3.90

Decorating a decorator – Mushroom pizza with corn addition

let mushroomPizzaWithCorn:Order = CornAdditionDecotator(mushroomPizza)
print(mushroomPizzaWithCorn.cost()) --> //4.30
