I’m trying to update the watchOS2 clockkit complication with the data transmitted by WatchConnectivity from IOS/iPhone.
Despite quite a lot of research, but It has not been successful so far. I found that other posts are describing similar challenges (no solution yet)
Facing 3 problems:
1) The sendMessage from ComplicationController does not seem to wake up IOS Parent App (the same sendMessage sent from InterfaceController at the same time will wake up IOS Parent App)
2) Even if the value is passed to ComplicationController (via sendUserInfoToComplication and when the IOS application is in the foreground), the value displayed in the complication Sometimes it also updates (the pattern is not found, why sometimes it will/sometimes not)
3) I set “getNextRequestUpdate ..” to 2 minutes (for testing purposes). But it doesn’t seem to have any Difference. (It can be triggered at any time even in the simulator, but the “budget” is not used / I set a plug to verify)
Please note that I am relatively new to IOS/Swift programming. But I think, based on other questions/posts, I don’t seem to be the only one struggling with this.
Here is the sample code:

In addition , When running the simulator, I received a lot of similar messages, as shown below:
objc[7501]: Class SPAssetCacheAssets is implemented in both /Applications/Xcode.app /Contents/Developer/Platforms/WatchSimulator.platform/Developer/SDKs/WatchSimulator.sdk/System/Library/Frameworks/WatchKit.framework/WatchKit and /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/ SDKs/WatchSimulator.sdk/System/Library/PrivateFrameworks/SockPuppetGizmo.framework/SockPuppetGizmo. One of the two will be used. Which one is undefined.
objc[7501]: Class SPAssetCacheSyncData is implemented in both /Applications/Xcode .app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/SDKs/WatchSimulator.sdk/System/Library/Frameworks/WatchKit.framework/WatchKit and /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/ Developer/SDKs/WatchSimulator.s dk/System/Library/PrivateFrameworks/SockPuppetGizmo.framework/SockPuppetGizmo.

< div class="answer"> Use CLKComplicationServer like this:
CLKComplicationServer* server = [CLKComplicationServer sharedInstance];
[server.activeComplications enumerateObjectsUsingBlock:^( CLKComplication * _Nonnull each, NSUInteger idx, BOOL * _Nonnull stop) {
[server reloadTimelineForComplication: each];
}];
It will call your ComplicationController.
