Pass Data From ViewController to TabBarController

I need to pass a username from the View Controller login screen to by Tab Bar Controller textfield.

I have tried the traditional method of doing this and am receiving a

"Could not cast value of type UITabBarController message.

If I don't try to pass the data, the tab bar controller loads fine.

//In my View Controller, I have tried this:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "GoToTabBar" {
        let custMainVC = segue.destination as! CustomerMainViewController
        custMainVC.tempName = self.emailTextField.text!

    }
}

//In my tab bar controller whose first View Controller has a name of CustomerMainViewController:

override func viewDidLoad() {
    super.viewDidLoad()
    username.text = self.tempName
}

Outcome is a Thread 1 and the debugger states: Reading from private effective user settings. Could not cast value of type 'UITabBarController'

I have cleared all my outlets and all the simple things that you may recommend, and as I stated if I remove the code to pass the data it is loading so this is not an outlet issue. Thanks for your help!!

The segue destination is the tabBar access it then you can get the first vc and pass the data

let custMainVC = segue.destination as! UITabBarController
let res = custMainVC.viewControllers!.first as! CustomerMainViewController
res.tempName = self.emailTextField.text!
