how to publish watchOS only apps to app store connect from xcode
Straight to the answer
To publish a Watch only app which uses HealthKit you not only need a plist file in your watchOS App project, you need one in the root of the Xcode solution.

Once youāve done this, make sure the Target Membership for all plist files in your solution are set to empty. If you donāt do this, your build will start failing.

Iāve published an App on the App Store! My first App is called One Big Thing and itās my take on every developerās first app being a todo app, with a twist: you only get one todo item per day.
My next app, Watch Hydration, is a watchOS exclusive that allows you to quickly log liquids to HealthKit straight from your watch. Itās currently on TestFlight, pending review.
Both of these apps are free and open source, and if anyone actually uses either of them Iāll be thrilled.
Okay, that said and done, Iām now going to write some words and sentences to attempt to catch search engines. Iām putting this below the answer, youāre welcome.
Xcode wonāt publish a Watch only app as itās asking for a .plist file with permission for NSHealthShareUsageDescription and NSHealthUpdateUsageDescription. I already have a .plist file with requested permissions for NSHealthShareUsageDescription and NSHealthUpdateUsageDescription but Xcode fails to distribute to TestFlight/App Store Connect. āBinary Rejectedā it declares, the nerve!
