tableView(_:heightForHeaderInSection:) not working

I am implementing a UITableView within my UIViewController. I have been able to get my text to display with a custom UITableViewCell, but I can not find a way to put spacing between my cells.

I have tried implementing tableView(_:heightForHeaderInSection:), but it seems that it is not called as I have tried to put in a print statement to see if it runs.

i had problem that heightForHeaderInSection was not working, but after i set viewForHeaderInSection then the height works properly. Make sure you have set the view header in section.

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let view = UIView.init(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 44))
    view.backgroundColor = .white
    return view
}

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
   return 44
}

Make sure that you set the tableview's delegate to be your viewcontroller (and make sure that your viewcontroller conforms to the UITableViewDelegate protocol):

class CustomTableViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet weak var tableView: UITableView! {
        didSet {
            tableView.dataSource = self
            tableView.delegate = self
        }
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return 5
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        return tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
    }

    func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 20
    }

}

Results in:

Add this in your viewDidLoad() :

let HEADER_HEIGHT = 100
tableView.tableHeaderView?.frame.size = CGSize(width: tableView.frame.width, height: CGFloat(HEADER_HEIGHT))

Another way - 

public override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 100
}
