Programmatically create NSTableView in Swift 4.1

SidebarViewController.swift

import Cocoa

class SidebarViewController: NSViewController, NSTableViewDelegate, NSTableViewDataSource {
    
    var initialized = false
    let scrollView = NSScrollView()
    let tableView = NSTableView()
    
    override func loadView() {
        self.view = NSView()
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    override func viewDidLayout() {
        if !initialized {
            initialized = true
            setupView()
            setupTableView()
        }
    }
    
    func setupView() {
        self.view.translatesAutoresizingMaskIntoConstraints = false
        self.view.addConstraint(NSLayoutConstraint(item: self.view, attribute: .width, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute, multiplier: 1, constant: 200))
    }
    
    func setupTableView() {
        self.view.addSubview(scrollView)
        self.scrollView.translatesAutoresizingMaskIntoConstraints = false
        self.view.addConstraint(NSLayoutConstraint(item: self.scrollView, attribute: .left, relatedBy: .equal, toItem: self.view, attribute: .left, multiplier: 1.0, constant: 0))
        self.view.addConstraint(NSLayoutConstraint(item: self.scrollView, attribute: .top, relatedBy: .equal, toItem: self.view, attribute: .top, multiplier: 1.0, constant: 23))
        self.view.addConstraint(NSLayoutConstraint(item: self.scrollView, attribute: .right, relatedBy: .equal, toItem: self.view, attribute: .right, multiplier: 1.0, constant: 0))
        self.view.addConstraint(NSLayoutConstraint(item: self.scrollView, attribute: .bottom, relatedBy: .equal, toItem: self.view, attribute: .bottom, multiplier: 1.0, constant: 0))
        tableView.frame = scrollView.bounds
        tableView.delegate = self
        tableView.dataSource = self
        tableView.headerView = nil
        scrollView.backgroundColor = NSColor.clear
        scrollView.drawsBackground = false
        tableView.backgroundColor = NSColor.clear
        tableView.appearance = NSAppearance(named: NSAppearance.Name.vibrantDark)

        let col = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "col"))
        col.minWidth = 200
        tableView.addTableColumn(col)
        
        scrollView.documentView = tableView
        scrollView.hasHorizontalScroller = false
        scrollView.hasVerticalScroller = true
    }
    
    func numberOfRows(in tableView: NSTableView) -> Int {
        return 100
    }
    
    func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {
        let text = NSTextField()
        text.stringValue = "Hello World"
        let cell = NSTableCellView()
        cell.addSubview(text)
        text.drawsBackground = false
        text.isBordered = false
        text.translatesAutoresizingMaskIntoConstraints = false
        cell.addConstraint(NSLayoutConstraint(item: text, attribute: .centerY, relatedBy: .equal, toItem: cell, attribute: .centerY, multiplier: 1, constant: 0))
        cell.addConstraint(NSLayoutConstraint(item: text, attribute: .left, relatedBy: .equal, toItem: cell, attribute: .left, multiplier: 1, constant: 13))
        cell.addConstraint(NSLayoutConstraint(item: text, attribute: .right, relatedBy: .equal, toItem: cell, attribute: .right, multiplier: 1, constant: -13))
        return cell
    }
    
    func tableView(_ tableView: NSTableView, rowViewForRow row: Int) -> NSTableRowView? {
        let rowView = NSTableRowView()
        rowView.isEmphasized = false
        return rowView
    }
    
}

How do we run this?
