SceneKit will be replaced by RealityKit on the other platforms, but on watchOS it has no replacement

I would also be interested in it for SpriteKit

You can add the other devices from Window -> Devices and Simulators in Xcode

Sure, you can use the update method in your SKScene (make sure to use delta time): https://developer.apple.com/documentation/spritekit/skscene/1519802-update

yourSprite.texture = yourNewTexture

@jhokit Yes, you're right. Actually we cannot add 41, 45 mm complications...
