Xcode 13.2 adds the Swift Playgrounds App project template that works with the upcoming version of Swift Playgrounds. The project template creates an iOS SwiftUI app. SwiftUI has a sprite view to show SpriteKit scenes so I tried adding a new SpriteKit scene to the project. Choosing File > New > File adds a Swift file to the project. The New File Assistant doesn't open.
I can add an existing SpriteKit scene to the project. I can view and edit the scene. I can also show the scene in a sprite view so I know this project template supports SpriteKit.
Adding an existing SpriteKit scene also adds a Resources folder to the project. When I choose to create a new file from the Resources folder, the New File Assistant opens. But SpriteKit Scene is not one of the file types I can add.
How do I add a new SpriteKit scene file to a Swift Playgrounds App project?
