how to convert .dae to .scn files in SceneKit

Question

This is a screenshot from Apple's Fox sample code. As you can see, they use .scn file format for graphics object. They explicitly state in the wwdc2015 video that this was done by an artist. So far I only worked with .dae and was until recently convinced that this is the only supported format. My question is, how do I export objects stored in .dae file to .scn file?

EDIT: this is what I get if go to Editor-> Convert to SceneKit scene file format (.scn)

Answer 1

Exporting the .dae is unnecessary; you can place the object directly into a .scn file:

Create the new .scn file in the .scnassets folder, then drag the .dae file into the scene.

Answer 2

open your DAE file in the SceneKit scene editor, then go to the Editor menu and click "Convert to scn file format".

Your artist won't be able to export a scn file from their favourite tool. You'll have to use Xcode to convert a DAE to SCN.
