I have a table view and I would like the user to select only one item from the table view, then I want to add a checkmark to the cell. At the same time, I also want the checkmark on other cells to disappear so the. user can only select one at a time. Then I want to save the data (preferably using UserDefaults). How do I do that?
Create a class variable of type IndexPath. In your cellForRowAt method set .checkmark accessory type only if index path matches the class variable and .none otherwise. In didSelectRowAt method update the indexPath of selected variable and just reload the tableview
