Using:
XCode 14.1 (single target watch app with existing iOS App)
iPhone XS Simulator with IOS 13, paired w/Watch Series 5 (44mm) Simulator , Watch OS 7, 8 or 9
I also get back:
IsPaired[true] isWatchAppInstalled[false] isReachable[false]
No issues with iOS 14, 15 or 16 Simulators, i.e.,
IsPaired[true] isWatchAppInstalled[true] isReachable[true]
It's only iOS 13.
I also went back to XCode 13.x, with two watch targets, and have the exact same issue. The above is preventing me from using method channel communications between iOS app and Watch app under iOS 13.
