Can anyone find out whether the Series 6 Watch can be used as a peripheral?

Same problem here. It happens on Xcode 12, XCode 12.2 beta 2 and Xcode 11.3.1. Have the latest Big Sur beta. Very critical as it's not allowing me to test apps on devices.

Same problem here, with Xcode 11, 12, 12 beta... Big Sur OS, happening weeks ago, re-installing Xcode and OS upgrade (beta-> release) didn't help. Any ideas???
