The manifest si here to declare the scene delegate you set up (even if it contains empty methods) as being your scene delegate, the one the app will use.

If you're using storyboards, you don't to fill up the scene delegate methods. Just set the storyboard name in the plist.
So yes, you need to add a manifest in your plist file.
You info.plist should look like this (assuming the name of your storyboard is "Main") :
info.plist

You shouldn't have black screen if you have your storyboard set up and declared in these (both) plist variables.

Hi Maarek,

Thank you for your quick response. I have the plist identical to yours. In the SceneDelegate I have the func scene empty. Still, I only get one black screen. What am I doing wrong?

Does your storyboard has an initial view controller set (with an arrow on the left) ?

Hi Maarek,

Yes I have activated an initial view controller. Do not understand why the screen stays black. As soon as I remove the manifest, the app goes back. Do you have any idea?

I Hi Maarek,

I am now a little closer to the goal. I had to paste this code into the scene delegate:

         guard let winScene = (scene as? UIWindowScene) else {return}

         // Create the root view controller as needed
         let vc = ViewController ()
         let nc = UINavigationController (rootViewController: vc)

         // Create the window. Be sure to use this initializer and not the frame one.
         let win = UIWindow (windowScene: winScene)
         win.rootViewController = nc
         win.makeKeyAndVisible ()
         window = win

Now the ViewController is displayed, but everything is crashed. TableView (found nil), present other view controller by button crash. What is going on here?

Hey! Have you had any resolution to this? I am also experiencing this issue of a black screen while using a Main storyboard.

Hi. I guess I figured it out. The

<key> Storyboard Name </key>

is wrong. It should be

<key> UISceneStoryboardFile </key>

. It made it work for me.
