define Grocery, Receipt

enum Grocery  {
  case wine(num: Int)
  case pork(num: Int)
  case onion(num: Int)

  func printRecipe() {
    switch self {
    case .wine(let num): print("\(num) Glasses")
    case .pork(let num): print("\(num) Pieces")
    case .onion(let num): print("\(num) pcs")
    }
  }
}

class Receipt {
  var grocerys: [Grocery] = []

  func add(grocery: Grocery) {
    grocerys.append(grocery)
  }

  func printRecipe() {
    grocerys.forEach { $0.printRecipe() }
  }
}

usecase

Grocery.onion(num: 10).printRecipe()

Grocery.pork(num: 2).printRecipe()

when using receipt model 

let receipt = Receipt()
receipt.add(grocery: .onion(num: 2))
receipt.add(grocery: .pork(num: 4))
receipt.add(grocery: .wine(num: 2))
receipt.printRecipe()

output

2 pcs
4 Pieces
2 Glasses
