Swift Custom Back Button and Destination

Question

I am currently using SWRevealViewController for a sidebar menu in my app. When I click one of the options, the destination view controller doesn't have a 'back' button because it hasn't come from a proper view controller (i.e. page to go back to).

Therefore I am wanting to manually create a back button on the destination view controller which will go back to the home view controller.

I have looked at the code here: How do I manually set the "Back" destination in iOS apps

But I am struggling to implement this in Swift (one error after another!). Any help? Thanks!

EDIT

I have tried the suggestion below, but the back button just doesn't appear. This may have something to with the fact I have the navbar hidden in other views and do the following on the destination view:

override func viewDidLoad() {     super.viewDidLoad()     navigationController.setNavigationBarHidden(false, animated:true)     var myBackButton:UIButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton     myBackButton.addTarget(self, action: "popToRoot:", forControlEvents: UIControlEvents.TouchUpInside)      var myCustomBackButtonItem:UIBarButtonItem = UIBarButtonItem(customView: myBackButton)     self.navigationItem.leftBarButtonItem = myCustomBackButtonItem }  override func didReceiveMemoryWarning() {     super.didReceiveMemoryWarning() }  func popToRoot(sender:UIBarButtonItem){     self.navigationController.popToRootViewControllerAnimated(true) } 

Not sure why the back button won't show up?

Edit

This is the prepareForSegue from my sidebar view controller. If there is a way to check for the segue identifier 'test' then I can set the back button from here?

- (void) prepareForSegue: (UIStoryboardSegue *) segue sender: (id) sender { // Set the title of navigation bar by using the menu items NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; UINavigationController *destViewController = (UINavigationController*)segue.destinationViewController; destViewController.title = [[_menuItems objectAtIndex:indexPath.row] capitalizedString];   if ( [segue isKindOfClass: [SWRevealViewControllerSegue class]] ) {     SWRevealViewControllerSegue *swSegue = (SWRevealViewControllerSegue*) segue;      swSegue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc) {          UINavigationController* navController = (UINavigationController*)self.revealViewController.frontViewController;         [navController setViewControllers: @[dvc] animated: NO ];         [self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];     };  }  }

You can write that in swift like this

Write this to add button on navigationController

    navigationController.setNavigationBarHidden(false, animated:true)     var myBackButton:UIButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton     myBackButton.addTarget(self, action: "popToRoot:", forControlEvents: UIControlEvents.TouchUpInside)     myBackButton.setTitle("YOUR TITLE", forState: UIControlState.Normal)     myBackButton.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)     myBackButton.sizeToFit()     var myCustomBackButtonItem:UIBarButtonItem = UIBarButtonItem(customView: myBackButton)      self.navigationItem.leftBarButtonItem  = myCustomBackButtonItem 

this will pops to rootViewController

    func popToRoot(sender:UIBarButtonItem){        self.navigationController.popToRootViewControllerAnimated(true)     }
