Displaying information within your glance controller

In the last section, we modified our interface controller class so that it can store information within our NSUserDefaults class and display the chosen shopping list product information within the Apple Watch glance interface controller.

In this section, we need to create the necessary code that will be responsible for retrieving information stored within our standardUserDefaults repository database and display the chosen shopping list product item within our glance. Perform the following steps:

1. Open the GlanceInterfaceController.swift file located within the ShoppingList WatchKit Extension group in the project navigation window.

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

   override func willActivate() {
           // This method is called when watch view controller 
           // is about to be visible to user
           super.willActivate()
           
           let userDefaults = NSUserDefaults.standardUserDefaults()
     ...
