I'm looking at this example of using watch connectivity by Apple
I've configured the app group and app identifiers, and the app compiles and runs on my phone, and a loading indicator appear on the watch. However, the app never appears on the watch.
The only message I get in the console is:
WCSession counterpart app not installed
I see the app I'm trying to install in the list of available apps on the Apple Watch App> Available apps. It has "install" button. Tapping the install shows loading indicator on the watch, but the app still fails to appear on the watch. I have another WatchOS app that I run from Xcode, and that one does appear on device, so I know it's possible to deploy app from Xcode
How do I resolve WatchOS app failing to install from Xcode (WCSession counterpart app not installed)?
