The next step in this tutorial is to design the user interface. This is a very simple user interface consisting of an image view, a toolbar and two bar button items. Select the Main.storyboard file and drag and drop components from the Library window (View -> Utilities -> Show Object Library) onto the view. Position and size the components and set the text on the bar button items so that the user interface resembles Figure 75-1.
