== The Target-Action pattern, IBOutlets and IBActions ==

When you create an iOS 8 app you will typically design the user interface (the view) using the Interface Builder tool and write the view controller and model code in Swift using the Xcode code editor. The previous section looked briefly at how the view controller interacts with the model. In this section we will look at how the view created in Interface Builder and our view controller code interact with each other.
