How to make SKScene appear in SwiftUI live preview for watchOS

Is there any way to make Xcode's live preview work with Sprite Kit Scenes? Here is my code for reference, I've tried a few different methods of constructing a SKScene but the live preview only displayed a blank scene. The sample scene works as expected when deployed to the simulator.

import SwiftUI
import SpriteKit

class GameScene: SKScene {
    override func sceneDidLoad() {
        print("scene loaded")
        physicsBody = SKPhysicsBody(edgeLoopFrom: frame)
        let shape = SKShapeNode()
        shape.path = UIBezierPath(roundedRect: CGRect(x: -128, y: -128, width: 256, height: 256), cornerRadius: 64).cgPath
        shape.position = CGPoint(x: frame.midX, y: frame.midY)
        shape.fillColor = UIColor.red
        shape.strokeColor = UIColor.blue
        shape.lineWidth = 10
        addChild(shape)
    }
}

struct GameView: View {
    var scene: SKScene {
        let scene = GameScene()
        scene.size = CGSize(width: 300, height: 400)
        scene.scaleMode = .fill
        return scene
    }

    var body: some View {
        SpriteView(scene: scene)
            .frame(width: 300, height: 400)
            .ignoresSafeArea()
    }
}

struct GameView_Previews: PreviewProvider {
    static var previews: some View {
        GameView()
    }
}
