Xcode 13 beta 2, iOS 15 beta 2, the following code produces a gray screen (the SKScene GameScene.didMove(to:) never gets called):
import SwiftUI
import SpriteKit
// A simple game scene with falling boxes
class GameScene: SKScene {
override func didMove(to view: SKView) {
physicsBody = SKPhysicsBody(edgeLoopFrom: frame)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
guard let touch = touches.first else { return }
let location = touch.location(in: self)
let box = SKSpriteNode(color: SKColor.red, size: CGSize(width: 50, height: 50))
box.position = location
box.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: 50, height: 50))
addChild(box)
}
}
// A sample SwiftUI creating a GameScene and sizing it at 300x400 points
struct ContentView: 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()
}
}
I have no idea how to fix / workaround this issue.
Any thoughts?

In Xcode beta 13, the documentation of NSPersistentContainer.loadPersistentStores(completionHandler:) goes like:
You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: func loadPersistentStores() async throws -> NSPersistentStoreDescription
However I couldn't call it like that as it complains about a Missing argument for parameter 'completionHandler' in call. E.g.:
do {
try await container.loadPersistentStores()
} catch {
// Handle error
}
Was it intentionally left aside? Perhaps it is to be added in future Xcode 13 versions?
