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

Answer 1

In storyboard-> Select your tableview-> go with property inspector-> And change type to Grouped from Plain

Answer 2

In Swift 5.0

The programatic way of doing this is to use UITableView.Style.grouped:

self.tableView = UITableView(frame: .zero, style: .grouped)
