I am having some trouble with adding the AddItemViewControllerDelegate on page 103 of Checklists. I have pasted in all the code from ChecklistViewController below, and have included the error messages in comments after the relevant parts of the code:

Your curly braces have gotten out of sync. All of these functions are intended to be a part of ChecklistViewController, but you have “closed” that class after tableView.commitEditingStyle() around line 98.

addItemVCDidcancel, addItemVCDidFinishAdding, configureCheckmark, configureText and prepareForSegue are all on the “outside” of the class they are intended for.

Try this: Cmd + A, then Control + I. This will select everything in your file, and then re-indent it. You will see how about half way down the file, your function declarations are no longer indented (because they are actually being placed outside of the class)

The quickest solution is to delete the extraneous “}” that is around 98.

Hope this helps

Thank you for pointing out the problem.  
I went back and just coded everything up to there again; I find doing it all over helps me to remember, as the more frequently I do it, the more I retain.  
Now I know I need to pay special attention to braces!  
Thank you.

+1 for this tip, so useful when you are lost in the bracesUniverse 😄
