Tried all of the above (including manual edit of entitlements file). In my failure case "Simulate Background Fetch" from Xcode does not cause the successfully registered BGAppRefreshTaskRequest to execute.

same thing. can't locate the capability in AppStoreConnect or developer profile to get Xcode to generate the appropriate entitlements file. Manually adding the fetch (or other desired) values to the entitlements file causes archive analysis to fail...

I have a semi-reliable means of getting things up and running. Reproducible? 🤷‍♂️ Some combination of: Shutdown xCode Unplug iPhone iPhone Settings > General > Reset > Transfer or Reset iPhone > Reset > Reset Location & Privacy Toggle developer setting on watch: Settings > Developer (restart) Plug in iPhone (potential long wait) Start xCode Re-plug iPhone (if the Xcode sync has succeeded with an error message to Trust this computer on iPhone) The key thing seems to be Trust This Computer? on iPhone being acknowledged three times. (One for iPhone?, one for Watch?, one for Xcode? I GUESS? 🤷‍♂️)
