I found the problem, I put it in the wrong view. Silly me 🤪.

We are supposed to create an Swift Playgrounds App

For anyone who is having the same issue, I fixed it by using ballEntity.move() instead and putting nothing as the rotation - let newTranslation = SIMD3<Float>(0, 0, 1) let moveController = ballEntity.move(to: Transform(scale: simd_make_float3(1, 1, 1), translation: newTranslation), relativeTo: ballEntity.self, duration: 0.2) whereas previously (not working) I was doing this: let newTranslation = SIMD3<Float>(0, 0, 1) let moveController = ballEntity.move(to: Transform(scale: simd_make_float3(1, 1, 1), rotation: anchor.orientation, translation: newTranslation), relativeTo: ballEntity.self, duration: 0.2) Removing the rotation: anchor.orientation helped as my anchor was a bit tilted or moving.

@CMDdev I also am having the Codesign failed with non-zero exit code error. I tried editing with Xcode closed and than opened it, and it still doesn't work. When I try to go back to the previous version of the file it says Package resolution failed; see package resolution log for details. Do you have any suggestions?
