new developer, need help displaying on screen

brand new newbie developer to xcode. so im doing an api call and getting back data from a mysql database. in the xcode preview window im getting data, but i cant figure out how to tie it to the screen when going into the simulator. i have screen 1 that i want to click a button to go to screen 2 that displays the data. screen one (home screen) comes up okay. cant quite figure out what im doing wrong here. im thinking its either a class issue or something to do with view or something. not sure. ive tried looking at so many different videos and i cant seem to find my answer. Any help would be appreciated. thank you

View Controller:

import UIKit

//import SwiftUI





let URL_TOURNAMENT_FETCH = "https://www.thesoftball.com/t2g_mobile_app/mobile_api.php"

class ViewController: UIViewController

{



    override func viewDidLoad() 

    {

        super.viewDidLoad()

        

        



    }



 

    @IBAction func onEmailButtonPressed(_ sender: Any) 

    {

        UIApplication.shared.open(URL(string: "mailto:[email]")! as URL, options: [:],completionHandler: nil)

    }

   

    /*

    @IBAction func FetchTournButton(_ sender: Any) {

        UIApplication.shared.open(URL(string: "https://www.thesoftball.com/t2g_mobile_app/mobile_api.php")! as URL, options: [:],completionHandler: nil)

    }

   */

    

    @IBAction func ViewTournamentButton(_ sender: Any)

    {

        // the following is a popup

        let alertController = UIAlertController(title: "Welcome to My First App", message: "Hello World", preferredStyle: UIAlertController.Style.alert)

                alertController.addAction(UIAlertAction(title: "OK", style: UIAlertAction.Style.default, handler: nil))

                present(alertController, animated: true, completion: nil)           



        

    }

    

    @IBAction func account_button_pressed(_ sender: Any) 

    {

        UIApplication.shared.open(URL(string: "https://www.thesoftball.com")! as URL, options: [:],completionHandler: nil)

    }

  /*

    struct viewDidLoadModifier: viewDidLoadModifier

    {

      @State private var didLoad = false

        private let action: (() -> void)?

        init(perform action)

        {

            

            

        }

    }

   */

    

}

ContentView (preview works in this)

import SwiftUI



 

struct ContentView: View {

    @StateObject var viewModel = ViewModel()

    var body: some View {

        NavigationView{

            List{

                ForEach(viewModel.courses,id: \.self) { tournament in

                    

                    HStack {

                        Image("")

                           .frame(width: 5, height: 120)

                           .background(Color.orange)

                        VStack {

                            Text(tournament.name).bold()

                        

                            Text(tournament.dates)

                            Text(tournament.datee)

                            Text(tournament.location)

                          //  Text(course.location)

                          //  Text(course.message)

                              //  .bold()

                        }

                    }

                    

                    

                    .padding(0)

                }

            }

            .navigationTitle("Tournaments")

            

           // .onAppear { viewModel.fetch()}

            .onAppear(perform: viewModel.fetch)

            

        }

    }

    

}


struct ContentView_Previews: PreviewProvider {

    static var previews: some View {

        ContentView()

    }

}
