This happened to me over the last few days. Xcode was being extremely unstable (sometimes, in the Build Scheme, it would say "paired watch unavailable for development", other times it would say "null" when referring to the watch, other times it would work!). I did all of the steps below, but the inconsistency was not solved:

Unpair my watch, Reboot both iPhone and apple watch, Pair them again, and setup my watch as a new one, Plug (unplug first) iPhone to Mac, On apple watch, say Trust the computer when it asks, Unplug and plug again
