great tutorial. Very cool.  
I’m having an issue setting the background image.  
scnScene.background.contents = “GeometryFighter.scnassets/Textures/Background\_Diffuse.png”  
displays a black image not blue. Please advise.

Same problem here. I resolved it by looking at the documentation for SCNScene. There is a Note saying “For best results, place scene files that ship in your app bundle in a folder with the .scnassets extension, and place image files referenced as textures from those scenes in an Asset Catalog…”  
So - here’s what I did:

1. Open Assets.xcassets and then drag Background\_Diffuse.png into the asset list.
2. Adjust the line in setupScene() so that it creates a new UIImage from that asset:  
scnScene.background.contents = UIImage(named: “Background\_Diffuse”)

Run the app. It should show the blue background now. This worked for me.
