Steps to set up a new iOS app without Storyboard(Main.storyboard removal):

1. Remove Main.storyboard
2. Clear Main storyboard file base name
3. Open info.plist and remove the property 'Storyboard name' under "Information property List > Application Scene Manifest > Scene Configuration > Application Session Role > Item 0(Default Configuration)"
4. And finaly in your SceneDelegate update the following.

From:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
 guard let _ = (scene as? UIWindowScene) else { return }
