Answer 1

I met this problem as well.

What I do is quite simple, turn off bluetooth from iPhone and turn on, wait till apple watch got connected again.

Then fire up the app.

Answer 2

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

Eventually, the I realised a slightly newer version of Mojave (10.14.5), and a slightly newer version of iOS (12.3.1) had been released. After I made these quick updates, XCode appears to be much more stable now.

Answer 3

I had issues with this too with Xcode 10.1 and Watch OS 5.x Really need delete Xcode Derived data files, and reboot Watch, and click 'Trust' button in Watch for debug.

Answer 4

I had the same issue with watchOS 2.1. Unplugging my phone restarting Xcode and plugin in my phone did the trick. I suggest trying that before you re-pairing phone and watch

Answer 5

I had the same issue on iOS 9.1 + WatchOS 2.01 that XCode 7.1 kept saying "paired device not available for development". Here is what I did to solve it finally, not quite sure which step is critical -

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

Bang! My apple watch is well recognized for development. Hope it helps.

Answer 6

Deleting the 'famous' XCODE Derived Data folder did it for me.

Steps for newbies:

1. Close XCODE.
2. Delete the Derived Data folder, to find it's location go in XCODE to upper menu: XCODE -> Preferences -> Locations: Here click on the Derived Data arrow.
3. Reopen XCODE.

Tested on XCODE8.0.
