Blueprinting the Shopping List Item model

Now that we understand the files and folders in our projects a little bit, let's start writing some code. We will begin by writing code for our first model, the Shopping List Item. To do so, perform the following steps:

1. Create a new group called Models under the ShoppingList folder in your project.
2. Then right-click and click on New File... under the Models folder and select a Swift file from the iOS template. Call this new file Item.swift and click Create.

 

3. Copy the following code into the Item.swift file:

import UIKit
class Item {
    var name: String
    var isChecked: Bool
    init(name: String, isChecked: Bool = false) {
        self.name = name
        self.isChecked = isChecked

We define a class calledItemwhich will serve as a blueprint for our Shopping List Items:

class Item {

We then define two properties to store a name for the item and the state of the item on whether it is checked or unchecked. These...
