Be sure to stretch the labels so that they both extend to cover most of the width of the view.

Select the top label object in the view canvas, display the Assistant Editor panel and verify that the editor is displaying the contents of the TouchMotionViewController.h file. Ctrl-click on the same label object and drag to a position just below the @interface line in the Assistant Editor. Release the line and in the resulting connection dialog establish an outlet connection named xCoord. Repeat this step to establish an outlet connection to the second label object named yCoord.
