All my sims disappeared when I installed Xcode 27 RC - this helped

This keeps coming back when I boot my mac, even if the option is off and there is no shortcut. Seems like a bug. macOS Sequoia 15.0 (24A335)

I'm also interested in knowing how to do this, and I have a feeling a lot of people are as well. Could you perhaps write som sample code to help us out? thx

To be a little bit more specific, what does the SCNMatrix4Mult(scnNode.worldTransform… do and scnNode.transform = matrix4 and = scnNode.simdWorldOrientation do? How can I write this in simd?

In my experience, I made a game with Scenekit and I had to descope a lot of simple things due to performance and limitations. SceneKit is written in Obj-C and uses CATransform's. But the biggest dissapointment was that Apple trashed it many years ago. If they don't support it - why should we!
