Crash Xcode 11, iOS13 setting root view controller

    let homeVC = UIStoryboard(name:"Main", bundle: nil).instantiateViewController(withIdentifier: "SigninViewController") as! SigninViewController
    let navC = UINavigationController(rootViewController: homeVC)
    navC.navigationBar.isHidden = true
    UIApplication.shared.windows.first?.rootViewController = navC
    UIApplication.shared.windows.first?.makeKeyAndVisible()
