On page 425-426, the screenshots show that the Icon Picker’s back button is “< Back”.
…but after following the tutorial, my Icon Picker’s back button is “< Add Checklist”.
I did add the segue by ctrl-dragging from Table View Cell in Section-2 of the Document Outline to the IconPickerViewController, and it works fine, but the back button text doesn’t match that of the tutorial.
If the previous view controller in the navigation stack does not have a title set, the back button will show “<Back” - otherwise it will show the title of the previous view controller. You don’t have to worry about this particular difference since it’s just a cosmetic one
