Use of undeclared type 'UITableViewSection' even though UIKit is imported

Question

I'm trying to create a reference to my TableView's static section. I control-drag the section from the Document Outline ("My Section", highlighted in the second screenshot) into the associated code file and Xcode offers to connect to a new UITableViewSection outlet (the "Type" field was pre-filled with "UITableViewSection"):

But then Xcode immediately complains telling me it doesn't know what UITableViewSection is:

I've imported UIKit, so that's not it. I can't find any documentation for UITableViewSection. It seems to not exist, but then why would Xcode let me drag it into the file to create an outlet?

Answer 1

You can not declare UITableViewSection like that, as there as no class available with that name. You can do it simply by creating a custom prototype UITableViewCell and can use it custom section header like below-

override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let cell = self.tableView.dequeueReusableCell(withIdentifier: "SectionHeader") as! CustomHeaderUITableViewCell
    return cell
}

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 60
}

Answer 2

I tried the same thing and same error occured. What i did was instead of creating an outlet on the section, i created an outlet on the Content View

@IBOutlet var editCountdownTableViewCell: UITableViewCell!

I am creating it because i want to be able to hide and show.
