After unpairing apple watch in xcode, I also had the issue that I was never able to see it again in Xcode until I did the following. Completely delete Xcode including deleting following files (chatgpt suggested, check before deleting) ~/Library/Developer/Xcode ~/Library/Preferences/com.apple.dt.Xcode.plist ~/Library/Caches/com.apple.dt.Xcode ~/Library/Developer/CoreSimulator/Devices Afterwards I deactivated and activated developer mode in iphone, and started new project. Watch became visible.
