Error in Extension Info.plist when submitting to TestFlight / iTunesConnect

[gylippus]

Has anyone able to submit a watch OS2 app using healthkit to Apple successfully? I keep running into this error:

ERROR ITMS-90362" :Invalid Info.plist value. The value for the key 'UIRequiredDeviceCapabilities' in bundle {bundle name} is invalid. Expecting array with a single string value of watch-companion'

Have been using the same entry as in the example:

<key>UIRequiredDeviceCapabilities</key>
    <array>
        <string>healthkit</string>
    </array>

That is what won't submit. If i change the string to watch-companion then the watch app will never start and is broken.
