I'm trying to get a particle effect across my whole background in storyboards using a SpriteKit view that I added but this keeps making my app crash. I tried to add it by code but this aswell crashed my app and I don't really know what to make out of the error message as I can't find much about it on the internet...

I linked my SpriteKit view with my 'MyParticle.sks' file

Full error message:

  • `scaleMode` is a property of `SKScene`, while it's being called in a `SKEmitterNode` instance. Show the stacktrace, it might help... – Larme Jun 23 '21 at 12:35
  • You mean the first throw call stack? I've added it! – Jef Janssen Jun 23 '21 at 12:46
  • In your ViewController, you have an IBOutlet of type SKsomething? Is it the correct class set to it? – Larme Jun 23 '21 at 12:47
  • Well I did not add a IBOutlet for the SKview, I just added the SKview and linked it to my particle.sks file but have not added code for it atm as I'm using storyboards. when I delete the SKview the app runs fine – Jef Janssen Jun 23 '21 at 12:52
  • Okay so if I remove the link between the SKview and my particle file, it renders the view with the standard grey color and doesn't crash the app, so I guess the problem is with the particle file – Jef Janssen Jun 23 '21 at 13:28
