I updated Xcode and since then I\'v problems with my dataBase. code:
override func numberOfSections(in tableView: UITableView) -> Int { // return the numb
Your method name for cellForRow is not correct.
Replace this line
func cellForRow(at indexPath: IndexPath) -> UITableViewCell? {
with
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
