If you need to get back to your tabbarcontroller from a view controller not connected to your tabbarcontroller, while using SWRevealController :)

menuTableViewController.swift

// This assumes you want the first button in your tableview cells to go back to the tabbarcontroller

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        
        if (indexPath.row == 0) {
            
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            // Give the tabbar an identifier in the storyboard
            let targetViewController = storyboard.instantiateViewControllerWithIdentifier("myTabBarController") as! UITabBarController
            targetViewController.selectedIndex = 0 // Your index you want to open
            self.revealViewController().pushFrontViewController(targetViewController, animated: true)
        
        } else {
            
            self.performSegueWithIdentifier("showAnotherViewController", sender: self)
        }
        
        
        
    }
