How to change separator height in UITableView Swift 3?

Question

Although there a few answers already on this topic. None of them cover Swift 3 and they are from a long time ago. What is currently the best way to change the separator heig

Answer 1

This is a correct way to do this.

First, in your ViewController you should set (tableView.separatorStyle = .none)

import UIKit 

class ViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.delegate = self
    tableView.dataSource = self
    tableView.separatorStyle = .none
   }

}

Second, in your TableViewCell class your should create a separatorView. And don't forget to inherit TableViewCell class for your cell.

class TableViewCell: UITableViewCell {

   override func layoutSubviews() {
      super.layoutSubviews()

      //Your separatorLineHeight with scalefactor 
      let separatorLineHeight: CGFloat = 1/UIScreen.main.scale

      let separator = UIView()

      separator.frame = CGRect(x: self.frame.origin.x, 
                               y: self.frame.size.height - separatorLineHeight,
                           width: self.frame.size.width,
                          height: separatorLineHeight)

      separator.backgroundColor = .black

      self.addSubview(separator)
   }

}

Finally, you've got a thin separator line and, of course, you can increase this value what do you like.
