iPhone: iOS 17.0 (21A5268h)
Apple Watch Ultra: watchOS 10.0 (21R5295g)
Xcode: Version 15.0 beta 2 (15A5161b)
macOS: 13.4.1 (22F82)
Xcode 15 beta 2 doesn't see my Apple Watch Ultra(watchOS 10), but Xcode 14.3.1 does. However, I cannot run on Xcode 14.3.1 because it doesn't support iOS 17 and watchOS 10.
Really frustrated, wasted all night debugging and failed. Maybe I have to return my watch to Apple Store on the weekend.
