Passing data with segue through TabBarControllerController

Question

Try this one Passing data with segue through navigationController but I need one more step before UITabBarController

ViewController->UITabBarController->UINavigationController->RestaurantTableViewController

The destination view controller of the segue is the UITabBarController. How can I get the real destination RestaurantTableViewController:

 override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == segueIdentifire() {
            let dcTabBar = segue.destination as! UITabBarController
            let dcNabBar = //i don't know what should i write here? 
            let dc = dcNabBar.topViewController as! RestaurantTableViewController
            dc.dcTitle = "Restaurant"

        }
    }

You can get the vc with dcTabBar.viewControllers?[0] (replace 0 with index) or just dcTabBar.selectedViewController if its the first tabbar item

could you write **prepare** method ? – Nazmul Hasan Nov 09 '16 at 08:37
This is for the part you said you dont know what you should write, the other part seems correct already – Tj3n Nov 09 '16 at 08:41
let dc = dcNabBar.topViewController as! RestaurantTableViewController this line error throwing Value of type 'UIViewController?' has no member 'topViewController' – Nazmul Hasan Nov 09 '16 at 08:51
have you put `as! UINavigationController` ? I missed that – Tj3n Nov 09 '16 at 08:53
yes but if i put as! UINavigationController then **unexpectedly found nil while unwrapping an Optional value** – Nazmul Hasan Nov 09 '16 at 08:54
Have you try both of the code above? Also try to print `dcTabBar.viewControllers?` to see if it hold any object – Tj3n Nov 09 '16 at 08:56

See if it working for you:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
      if segue.identifier == "toTabController" {
        var tabBarC : UITabBarController = segue.destinationViewController as UITabBarController
        var desView: RestaurantTableViewController = tabBarC.viewControllers?.first as RestaurantTableViewController

        var caseIndex = overviewTableView!.indexPathForSelectedRow()!.row
        var selectedCase = self.cases[caseIndex]

        desView.caseitem = selectedCase
      }
    }
