Note from the Author or Editor:
The crossword needs to be updated to change the answer to NSSTRING - so both crossword forge files will need to be updated to add a square.

The cursive callout text refers to "DetailedDrinkViewController" when it should be "DrinkDetailViewController" …just like the DetailedDrinkViewController… should read …just like the DrinkDetailViewController… No big deal but it made me panic and go back through all the code thinking i had used the wrong name!

Note from the Author or Editor:
Change "DetailedDrinkViewController" to "DrinkDetailViewController" in the annotation at the top of the page.
