ios XCTest failed Could not find a storyboard named LaunchScreen in bundle NSBundle - swift

Question

I'm trying to run a simple test case where I want to test my view controller but I'm getting this error
Could not find a storyboard named 'LaunchScreen' in bundle NSBundle
I'm running a cocoapods lib through the example folder
this is my test case:
import XCTest
#testable import Welcome
class WelcomeViewControllerTests: XCTestCase {
var viewModel: WelcomeViewModelProtocol!
var viewController: WelcomeViewController!
override func setUpWithError() throws {
viewModel = WelcomeViewModel()
viewController = WelcomeViewController(viewModel: viewModel)
viewController.viewDidLoad()
}
override func tearDownWithError() throws {
viewModel = nil
viewController = nil
}
func testLoadLaunchScreen() throws {
viewController.loadLaunchScreen()
}
}
This is my viewController:
import UIKit
public class WelcomeViewController: UIViewController {
private var viewModel: WelcomeViewModelProtocol
public override func viewDidLoad() {
super.viewDidLoad()
loadLaunchScreen()
let string = viewModel.fetchExample()
debugPrint(string)
}
public init(viewModel: WelcomeViewModelProtocol) {
self.viewModel = viewModel
super.init(nibName: nil, bundle: nil)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func loadLaunchScreen() {
let storyboard = UIStoryboard(name: "LaunchScreen", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "LaunchScreen")
navigationController?.isNavigationBarHidden = true
navigationController?.pushViewController(vc, animated: false)
}
}
