Segueing to a different tab in a UITabController

I am trying to segue data from my "create a party" form into my second "Find Parties" tab.

Here is a screen shot of my main story board:

main story board

my code for the create a party controller:

import UIKit

struct party {
    var name: String
    var location: String
    var description: String
}

class FirstViewController: UIViewController {

    @IBOutlet weak var nameField: UITextField!
    @IBOutlet weak var locationField: UITextField!
    @IBOutlet weak var descriptionField: UITextView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    var newParty = party(name: "", location: "", description: "")

    @IBAction func create(_ sender: AnyObject) {
        newParty = party(name: nameField.text!, location: locationField.text!, description: descriptionField.text!)
        nameField.text = ""
        locationField.text = ""
        descriptionField.text = ""
        performSegue(withIdentifier: "toPartyList", sender: newParty)
    }

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        let destinationViewController : SecondViewController = segue.destination as! SecondViewController
        destinationViewController.parties.append(newParty)
    }

}

Code for the find parties tab:

import UIKit

class SecondViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    @IBOutlet weak var partyTable: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        partyTable.delegate = self
        partyTable.dataSource = self

        // updates the table of users everytime submit is clicked
        DispatchQueue.main.async{
            self.partyTable.reloadData()
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

     var parties = [party]()

    // creates the number of cells in the table
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return parties.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        // Make table cells the show the user name
        let cell = UITableViewCell()
        cell.textLabel?.text = parties[indexPath.row].name
        return cell
    }

    // Allows the user to swipe and delete people from the table and also the users array
    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

        if editingStyle == .delete {

            // delete the person in users array
            parties.remove(at: indexPath.row)

            // delete the cell from the table
            partyTable.deleteRows(at: [indexPath], with: .fade)
        }
    }


}

currently my segue just takes me directly to the "Find Parties" view controller with no way back, and not to the tab. what do I need to change in my segue to do this?

Rather than use a segue in this case, just switch tabs programatically:

@IBAction func create(_ sender: AnyObject) {
    newParty = party(name: nameField.text!, location: locationField.text!, description: descriptionField.text!)
    nameField.text = ""
    locationField.text = ""
    descriptionField.text = ""
    tabBarController?.selectedIndex = 1 // 2nd tab
}

To pass information along, you can do something like this:

let navVC = tabBarController.viewControllers[1] as! UINavigationController
let rootVC = navVC.viewControllers[0] as! SomeViewController
rootVC.someData = myData
