When I try to upload my iOS + apple watch app to iTunes using Application Loader, I get the error message
ERROR ITMS-90595: "Unsupported Key. The Info.plist of bundle Watchless.app/Watch/WatchlessWatchApp.app/PlugIns/WatchlessWatchApp Extension.appex may not contain the UIRequiredDeviceCapabilities key."
Info.plist contains
<key>UIRequiredDeviceCapabilities</key>
<array>
<string>healthkit</string>
</array>
which I think is absolutely necessary because both, watch app and iOS app depend heavily on HealthKit.
The entry is generated when I turn on the HealthKit capability of the watch extension target.
I am running out of ideas what to change.
Using XCode 7.2, Application Loader 3.4
