Hey,

Just a quick heads up, over the next lessons we will be changing up the code in our app. As such, clicking the add button will cause the app to crash and you will see output like this in the debug console:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Attempt to insert non-property list object (

    "Todoey.Item",

    "Todoey.Item",

    "Todoey.Item"

) for key ToDoListArray'

We will update the code for the add button in a later lesson, so I recommend only running the app when you see me doing so in the videos. Ignoring this problem until we finish writing all the code required to handle the click.

All the best,

Your Instructor, Angela
