Swift – Table View reloadData not working after editing contents of cell - ios

Question

In my app, I'm showing user a table view of entries and when they tap on one, they're taken to a screen with a TextView so they can edit the contents of that cell. When they save, they're transitioned back to the tableView. The problem is that the data isn't reloading when they return to the tableView, it shows the same data as before they edited the contents of a cell
I've tried putting self.tableView.reloadData() in both viewWillAppear and viewDidAppear but neither are working. I've read a bunch of answers pertaining to this and none have worked. I'd love your help. Thanks!

add prepareEntries() in viewWillAppear
