Before a test run of the application can be performed the image files referenced in the code need to be added to the project. An archive containing the images may be found in the attractionImages folder of the code sample archive which can be downloaded from the following URL:

Select the Assets.xcassets entry in the Project Navigator panel, Ctrl-click in the left-hand panel of the asset catalog screen and select the Import… menu option. In the file selection dialog, navigate to and select the attractionImages folder and click on the Open button to import the images into a new image set.
