I have a regular .sks file in Xcode9, TestScene.sks.
Of course, you need SKView to hold .sks.
If I manually create SKView in the code in the usual way, it works fine. (I have included a handy example of this at the bottom of this post.)
However, in X9, you can simply add SKView to the storyboard .
And then just select the .sks file in the attribute check ....

But.
This does not work. I just get this error:
Main.storyboard: Class Unavailable Xcode.IDEInterfaceBuilder.CocoaTouch.SKView
What is the problem?
SpriteKit.framework is included in Link Binary ...
What could be the reason?
Point 1: to record how to manually add the code:
func manuallyAddSceneInCode() {
let sk: SKView = SKView()
sk.frame = view.bounds
sk.backgroundColor = .clear
view.addSubview(sk)
let scene = SKScene(fileNamed: "TestScene")!
scene.scaleMode = .aspectFit
scene.backgroundColor = .clear
sk.presentScene(scene)
}
