Found a Bug in the code

Found one bug in the coding provided. Whenever i edit a cell and change the text inside the textfield, the changes does not show immediately. The change of text appears only after relaunching the app. Wonder who gets this bug too.

Huh your right that is a problem on the device. I only checked it in the simulator. Try this in ToDoListController:

    override func viewWillAppear(_ animated: Bool) {
        tableView.reloadData()
    }

This should reload tableView for you.

Works fine for me. Go back through the sections titled 'Fetching Data Using Fetch Requests'.

Hi Brandon. Yes it seems to work fine. But i'm not sure if you've tested this out. 1) Try editing one of the cell. 2) When editing in Detail View Controller, delete whatever to-do-task you've entered in the textfield. 3) Try copying some words or sentences and paste it in the textfield and save it. 4) When you're in ToDoListController, do you still see the cell that you've updated? In my case, it didn't show the updated text that i've just saved, instead it shows the previous one. But when you click on the cell, you'll actually see the updated one inside detail view controller but not in ToDoListController.

It works well if you type in the textfield instead of copy & paste texts. I'm not sure why though.

Fyi, i've even downloaded and tested on the project file that is provided and it appears the same.
