The icon is still not there in Xcode 26.1 beta running on macOS or iPad device. The Metal Capture GPU workload icon is present. If I run the BOT-anist sample app on visionOS simulator, the icon is there, but I'm not supporting visionOS in my app.

With the help of this thread here: https://developer.apple.com/forums/thread/649579 I was able to do this. Specifically the three-part comment from annca. However, I did have to compromise by removing the bridging header, and creating a Swift file with the duplicate enumerations and structures from the bridging header.
