Why am I getting two different screen dimensions in different projects (Swift)?

I just finished a very rough draft of my first app whilst learning Swift. So I decided to remake the app so that my code would be cleaner/more compliant, etc.

I don't use storyboards, I launch from GameViewControler, both apps are set for a minimum iOS of 13.5, and both are run on the iPhoneX simulator...as well as my iPhoneX itself.

But for some reason in each different app, I am getting different screen sizes! Am going to assume I did something different when I "created" the new project, but am unable to distinguish what that is.

Here is my entire GameViewController.swift file and have included a photo of the different screen sizes. I break right after I get both the bounds and native bounds.

The two different sizes are:

In the 1st project I get

wPixels 1125
hPixels 2436
wPoints 375
hPoints 812

and the 2nd

wPixels 960
hPixels 1440
wPoints 320
hPoints 480

import UIKit
import SpriteKit
class GameViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        if let view = self.view as! SKView? {
            var wPix = UIScreen.main.nativeBounds.width
            var hPix = UIScreen.main.nativeBounds.height
            var wPoi  = UIScreen.main.bounds.width
            var hPoi  = UIScreen.main.bounds.height
            var scene : GameScene!
            DispatchQueue.main.async { [self] in
                     scene = GameScene(size: CGSize(width: wPoi, height: hPoi))
            scene.anchorPoint = CGPoint(x: 0.0, y: 0.0)
            scene.backgroundColor = .red
            scene.scaleMode = .aspectFit
            view.isHidden = false
            view.presentScene(scene)
            }
            view.ignoresSiblingOrder = true
            view.showsFPS = true
            view.showsNodeCount = true
            view.showsPhysics = true
        }
    }
    override var shouldAutorotate: Bool {
        return false
    }
    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        if UIDevice.current.userInterfaceIdiom == .phone {
            return .allButUpsideDown
        } else {
            return .all
        }
    }
    override var prefersStatusBarHidden: Bool {
        return false
    }
