Select the label object in the view canvas, display the Assistant Editor panel and verify that the editor is displaying the contents of the ViewController.swift file. Ctrl-click on the same label object and drag to a position just below the class declaration line in the Assistant Editor. Release the line and, in the resulting connection dialog, establish an outlet connection named statusLabel.

Next, the non-visual gesture recognizer objects need to be added to the design. Scroll down the list of objects in the Object Library panel until the Tap Gesture Recognizer object comes into view. Drag and drop the object onto the View in the design area (if the object is dropped outside the view, the connection between the recognizer and the view on which the gestures are going to be performed will not be established). Repeat these steps to add Pinch, Rotation, Swipe and Long Press Gesture Recognizer objects to the design. Note that the document outline panel (which can be displayed by clicking on the panel button in the lower left-hand corner of the storyboard panel) has updated to reflect the presence of the gesture recognizer objects as illustrated in Figure 56-1. An icon for each recognizer added to the view also appears within the toolbar across the top of the storyboard scene.
