The next question was about performance assets.
Merging or aligning background nodes to improve game performance?
βMake sure your atlas is not broken in a way that adds to the draw.β
"If you use xcassets to execute your current atlas, I would recommend returning to the regular .atlas folder until the apple fixes the error inside xcassets, causing the drawing counter to increase sharply."

I am trying to improve performance. I am currently using Xcode Version 9.0.1 (9A1004). My assets are set up as follows.

So, I tried following this advice by renaming my .xcassets folders
eg. 
However, this made my game go from
Icon before changing to .atlas 
Gameplay before changing to .atlas 
Icon after changing to .atlas 
Gameplay after changing to .atlas 
How is it not easy to fix ...
sprite-kit xcode9 xcasset
