just ignore this comment of mine for now

I checked it more deeply and it seems that it also affect SCNGeometrySource for .color semantic

I solved this problem by porting app to iOS. There I realised that I need typealias for CGFloat vs. Float so I made SCNFloat. Then when I replaced it everywhere including the parameter of SCNGeometrySource it seems to be solved. bytesPerComponent: MemoryLayout<SCNFloat>.size,
