I am having a problem while adding sections to my dynamic view. I want 4 different sections but I only want to add to one of the sections via my textfield.
I have tried this method over here: How to deal with dynamic Sections and Rows in iOS UITableView
Which I believe is on the right track however when I add something it doesn't show up which means I must be returning something wrong right? I just can't wrap my head around this!
The code below does not have any code in it from stackoverflow question above!

newItem.dateCreated = Date()
currentCategory.items.append(newItem)
}
}
catch
{
print("Error saving new items, \(error) ")
}
//If text field is empty - Show error message
}
self.tableView.reloadData()
}
}
// MARK: - Implement Search Bar Methods
// Using extension to seperate out functionality
extension TodoListViewController: UISearchBarDelegate {
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
todoItems = todoItems?.filter("title CONTAINS[cd] %@", searchBar.text!).sorted(byKeyPath: "dateCreated", ascending: true)
tableView.reloadData()
}
// Finish write on search bar, change condition to the first view
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if searchBar.text?.count == 0 {
loadItems()
// Being run in the background
DispatchQueue.main.async {
searchBar.resignFirstResponder()
}
}
}
}
The expected results should be that there should be 4 sections created and one of the sections should be filling up with the textfield. Like my code does already just not in the whole table but in one of the sections
