Scheduling notifications with your notification controller

In this section, we will look at how we can set up and schedule notifications using the UIApplication and UILocalNotification classes to send notification messages once an order is successfully processed so that it can then be displayed within the dynamic notification controller class. Here are the steps:

1. Open the AppDelegate.swift file located within the ShoppingList group in the project navigation window.

2. Next, locate the didFinishLaunchingWithOptions method and enter the following highlighted code snippet:

   func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

      let notificationCategory:UIMutableUserNotificationCategory =
      UIMutableUserNotificationCategory()
   
      // Initialize our Notification Category
      notificationCategory.identifier = "ORDER_PLACED"
           
      // Register our Notification...
