Swift side bar menu complies but does not appear - swift

Question

I have been to following this guide [https://www.youtube.com/watch?v=qaLiZgUK2T0] for the creation of a swift sidebar menu: The code compiles, with out errors... I must be missing something simple somewhere....The menu does not appear. Please assist me with locating this issue.
The code for the menu is listed below in three files:
ViewController.swift:
import UIKit
class ViewController: UIViewController, SideBarDelegate {
var sideBar:SideBar = SideBar()
override func viewDidLoad() {
super.viewDidLoad()
sideBar = SideBar(sourceView: self.view, menuItems: ["first item","second item","third item"])
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func sideBarDidSelectButtonAtIndex(index: Int) {
}
}
SideBarTableViewController.swift:
import UIKit
protocol SideBarTableViewControllerDelegate{
func sideBarControlDidSelectRow(indexPath:NSIndexPath);
}
class SideBarTableViewController: UITableViewController {
var delegate:SideBarTableViewControllerDelegate?
var tableData:Array<String> = []
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return tableData.count;
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("Cell") as? UITableViewCell
if cell == nil{
cell = UITableViewCell(style :UITableViewCellStyle.Default, reuseIdentifier: "Cell")
// Configure the cell...
cell!.backgroundColor = UIColor.clearColor()
cell!.textLabel.textColor = UIColor.darkTextColor()
let selectedView:UIView = UIView(frame: CGRect (x: 0, y:0, width: cell!.frame.size.width, height: cell!.frame.size.height))
selectedView.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.3)
cell!.selectedBackgroundView = selectedView
}
cell!.textLabel.text = tableData[indexPath.row]
return cell!
}
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat{
return 45.0
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
delegate?.sideBarControlDidSelectRow(indexPath)
}
}
SideBar.swift
import UIKit
#objc protocol SideBarDelegate{
func sideBarDidSelectButtonAtIndex(index:Int)
optional func sideBarWillClose()
optional func sideBarWillOpen()
}
class SideBar: NSObject, SideBarTableViewControllerDelegate {
let barWidth : CGFloat = 150;
let sideBarTableViewTopInset:CGFloat = 64.0;
let sideBarContainerView: UIView = UIView()
let sideBarTableViewController: SideBarTableViewController = SideBarTableViewController()
let orginView : UIView!
var animator: UIDynamicAnimator!
var delegate:SideBarDelegate?
var isSideBarOpen:Bool = false

}

sideBarContainerView.backgroundColor = UIColor.clearColor()
sideBarContainerView.clipsToBounds = false

let blurView:UIVisualEffectView = UIVisualEffectView(effect:

}
func handleSwipe(recognizer:UISwipeGestureRecognizer){
if (recognizer.direction == UISwipeGestureRecognizerDirection.Left){
showSideBar(false)

}else{

}
}
func showSideBar(shouldOpen:Bool){

let gravityX:CGFloat = (shouldOpen) ? 0.5 : -0.5

sideBarBehavior.elasticity = 0.3
animator.addBehavior(sideBarBehavior)
}
func sideBarControlDidSelectRow(indexPath: NSIndexPath) {
delegate?.sideBarDidSelectButtonAtIndex(indexPath.row)
}
}

I went through and debugged the project file when you download the source code and all I had to do to get it to work was make a bunch of minor changes to the SideBarTableViewController.swift and everything worked for me. Here it is:
import UIKit
protocol SideBarTableViewControllerDelegate{
func sideBarControlDidSelectRow(indexPath:NSIndexPath)
}
class SideBarTableViewController: UITableViewController {
var delegate:SideBarTableViewControllerDelegate?
var tableData:Array<String> = []
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return tableData.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("Cell") as? UITableViewCell
if cell == nil{
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
// Configure the cell...
cell?.backgroundColor = UIColor.clearColor()
cell?.textLabel?.textColor = UIColor.darkTextColor()
let selectedView:UIView = UIView(frame: CGRect(x: 0, y: 0, width: cell!.frame.size.width, height: cell!.frame.size.height))
selectedView.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.3)
cell!.selectedBackgroundView = selectedView
}
cell?.textLabel?.text = tableData[indexPath.row]
return cell!
}
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 45.0
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
delegate?.sideBarControlDidSelectRow(indexPath)
}
}
