Sorting an array of products

In this recipe, we will learn how to manage an array in Swift. Here, we will create an array of products (very typical), add products to it, remove unavailable products, and sort the array by price.

Getting ready

Create a new Swift single view project called Chapter 2 SortingProduct.

How to do it...

Let's create and sort an array of products by following these steps:

1. Before we start with the view part, let's create the model part of our application. In our case, we will create the Product class. So, create a new file called Product.swift and type the following code:

   class Product: Printable {
       var name:String
       var price:Double
       var available:Bool
       
       init(name:String, price:Double, available:Bool){
           self.name = name
           self.price = price
           self.available = available
       }
       
       var description: String {
           return "\(self.name): \(self.price)£ available: \(self.available)"
       }
   }

2. As you can see, the idea...
