Hi Josemaria, I was able to follow along this tutorial in Swift Playgrounds on my iPad Pro 2018 (without Lidar): https://www.ralfebert.com/ios/realitykit-dice-tutorial/ This is a tutorial that starts off from scratch and builds the app step by step. I added Camera under App Capabilities to get going, and then entered the code as described in the tutorial. Every time it told me to Run the app, I did so, and it worked. Hopefully this will work for you also.
