Getting an error when adding item, Chapter 13

[tmacka]

Hi - I’m getting an error when clicking on ‘done’ after adding an item. I have tried comparing the code with the downloaded project, but it says it is the same. The segue identifier is named on the storyboard, and I’m really stuck and would appreciate any help please. My project is at:

GitHub - tmacka/Checklists

The error I’m getting is:

Thank you

It is something about the connection of the doneBarButton to the done() action.

Does the cancel button work? Your declarations of these two actions are different:

    @IBAction func cancel(_ sender: UIBarButtonItem) {
    
    @IBAction func done() {

You might try making the done one

    @IBAction func done(_ sender: UIBarButtonItem) {

Or just remove the action link on the storyboard, and then redo it. Storyboards are one place where it is harder to compare your version and the tutorial version.

Thanks - I eventually found the wrong connection and it now works!
