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
