I am trying to update a watchOS2 clockkit complication with data transferred via WatchConnectivity from IOS / iPhone.
Despite quite a bit of research, so far unsuccessful. I found though that other posts are describing similar challenge (with no solution yet)
Am facing 3 problems:
1) sendMessage from ComplicationController does not seem to wake the IOS Parent App (whilst the same sendMessage sent from InterfaceController does wake IOS Parent App up)
2) even when value is transferred to ComplicationController (via sendUserInfoToComplication and when IOS app is in foreground), the value displayed in the complication only sometimes gets updated (haven't found pattern why sometimes it does / sometimes not)
3) I set "getNextRequestUpdate.." to 2 minutes (for test purposes). This does not seem to make any difference though. (gets triggered even in simulator at arbitrary times, but "budget" is not utilised / I set stoppers to verify)
Please note that I am relatively new to IOS / Swift programming. But I see, based on other questions / posts, that I do not seem to be the only one struggling with this.
Here the sample code:

Also, when running Simulator, I get a whole number of similar messages to the following:

One of the two will be used. Which one is undefined.
