I have updated this question as I found another key to this problem. It seems that when I add something to CoreData, the tableview does not reload the data, even though I can pr
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
fetchedResultsController.delegate = nil
self.tableView.reloadData()
}
maybe try this:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
self.tableView.reloadData()
}
