Swift 2 Blueprints

The models

Let's create some models before we start with any visual part for the app. First, add a new file called Supply.swift. Here, we are going to create a class that represents some supplies, which can be of the drink, food, and dessert types. To differentiate them, we are going to create an enumeration called SupplyType:

enum SupplyType:String{
    case Drink = "drink", Food = "food", Dessert = "dessert"
}

Tip

Now, we need to create the Supply class. In this class, we need an attribute for the supply's name, another one for its type, and two private ...
