SKView does not cover the entire screen area

I started studying SpriteKit recently with one famous textbook and immediately a problem arose. In all video lessons, SKView covers the entire display area. I have the opposite situation and I don't know how to fix it. Here are the screenshots:

Here is the source code:

GameViewController.swift:

import UIKit
import SpriteKit

class GameViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Set the scale mode to scale to fit the window
    
        let skView = self.view as! SKView
        skView.showsFPS = true
        skView.showsNodeCount = true
        skView.ignoresSiblingOrder = true
    
        let scene = GameScene(size: CGSize(width: 2000, height: 1500))
        scene.scaleMode = .aspectFill
        // Present the scene
        skView.presentScene(scene)
    }

    override var shouldAutorotate: Bool {
        return true
    }

    override var prefersStatusBarHidden: Bool {
        return true
    }
}

GameScene.swift:

import SpriteKit

class GameScene: SKScene {
    override func didMove(to view: SKView) {
        backgroundColor = .brown
    }
}

I don't know if anyone had such problems before the macOS 11 and Xcode 12, but now they are. How to stretch SKView across all screen?

Set your project's Lauch screen file to "Main".
