Try running the below code to know where you have gone wrong.

let storyboard = UIStoryboard(name: "Main", bundle: nil)
guard let playGameViewController = storyboard.instantiateViewController(withIdentifier: "PlayGameViewController") as? PlayGameViewController else {
    print("This means you haven't set your view controller identifier properly.")
    return
}
guard let navigationController = navigationController else {
    print("This means you current view controller doesn't have a navigation controller")
    return
}
navigationController.pushViewController(playGameViewController, animated: true)

Try using breakpoints to figure out if any variable is nil. In your case, there is more probability for having your navigationController being nil.
