I have tried below Code. It is navigate to StoreDetails View Controller.Not displaying Tab Bar Items

let storeDetails = self.storyboard?.instantiateViewController(withIdentifier: "StoreDetailsController") as! StoreDetailsController
        storeDetails.managedContext = managedContext
        storeDetails.coreData = coreData
        storeDetails.back = true
self.navigationController?.pushViewController(storeDetails, animated: false)

Answer 1

Since it is interconnected . pushToViewController or popTOViewController or dismiss is not worked. so I have used unwind.

StoreDetailsController: I have below code in StoreDetailsController

@IBAction func unwindToVC1(segue:UIStoryboardSegue) {
        print("Test")
    }

In my ShoppingListViewController I have unwind Done bar button to exit.

 @IBAction func done(_ sender: UIBarButtonItem) {
performSegue(withIdentifier: "unwindSegueToVC1", sender: self)
       }

you can follow the below link for unwind
