Adjust tableView height by code in Swift

I am trying to automatically adjust the table view height in my project, by determining what kind of iPhone the user has. However, I am not quite sure how I would proceed in order to adjust the height. I have tried several methods such as self.tableView.rowHeight = 100 etc, but with no luck.

Could someone please point me in the right direction?

Thanks in advance.

First, create an extension to detect which iPhone is running the app:

extension UIDevice {
    var iPhone: Bool {
        return UIDevice().userInterfaceIdiom == .phone
    }
    enum ScreenType {
        case iPhone4
        case iPhone5
        case iPhone6
        case iPhone6Plus
        case unknown
    }
    var screenType: ScreenType {
        guard iPhone else { return .unknown }
        switch UIScreen.main.nativeBounds.height {
        case 960:
            return .iPhone4
        case 1136:
            return .iPhone5
        case 1334:
            return .iPhone6
        case 2208:
            return .iPhone6Plus
        default:
            return .unknown
        }
    }
}

Then, in your controller, link the tableview delegate if you didn't do it yet:

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.delegate = self
    tableView.dataSource = self
}

Implement the delegate method like so to adjust height of cell depending on iphone type:

extension YourViewController: UITableViewDelegate {
    override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        switch UIDevice().screenType {
        case .iPhone4:
            return 40
        default:
            return 60
        }
    }
}
