Fixed landscape mode with SwiftUI and Spritekit Scene

I have a pretty standard Spritekit Scene that loads from a SwiftUI view. All settings are set to landscape only. Scene dimensions are correct. How can I stop the GameScene from rotating when I go into portrait mode? I didn't have this issue when using regular Swift before. Is this a SwiftUI issue?

Also I have managed to get my Preview window to be in Landscape but when I run Live Preview it returns to portrait.

This is my ContentView code with the SKScene.

struct ContentView: View {

    

    var scene: SKScene {

        let scene = GameScene()

        scene.size = CGSize(width: 1080, height: 800)

        scene.scaleMode = .fill

        scene.backgroundColor = .black

        

        return scene

    }

    

    var body: some View {

        SpriteView(scene: scene)

            .frame(width: 1080, height: 800, alignment: .center)

            

    }

    

}



struct ContentView_Previews: PreviewProvider {

    static var previews: some View {

        ContentView()

            .previewDevice("iPad (8th generation)")

            .previewLayout(.fixed(width: 1080, height: 800))

            

            

        

    }

}
