On the part where I tap from SplashScene to GameScene I get the following error message:

-[MTLDebugRenderCommandEncoder validateFramebufferWithRenderPipelineState:]:1196: failed assertion `For color attachment 0, the render pipeline’s pixelFormat (MTLPixelFormatRGBA8Unorm\_sRGB) does not match the framebuffer’s pixelFormat (MTLPixelFormatBGR10\_XR\_sRGB).’  
(lldb)

I don’t get this error message on the simulator but only when I use my iPhone 8 plus. Does anyone know how to fix this issue? I can do fine any other tutorials but this only happen with Mr.Pig

Thanks in advance for your time.

Hi there, the issue is related to an existing bug within SceneKit and Transitions while debugging. Please checkout [this](https://forums.kodeco.com/t/chapter-19-challenge-error/24307) thread, there’s some ideas how to deal with the bug.

Thank You, I tried both workarounds but the only one that worked for me was editing the scheme. I noticed when the screen switches from the splash to the game scene there is like a 2 seconds green pixel moment then it loads the game scene. It’s pretty weird but hey it’s a work around, Thank You for the quick response.
