Adobe Experience Platform Data Collection

Hi Adobe Team,

I have integrated new Mobile Core library into my iOSProject(Objective -C). 

  ACPCore.trackState("SomeView", data: nil)

Trying to use track-state in one of my controller . Getting below error in my Xcode Console. 

Error:

[AdobeExperienceSDK DEBUG <com.adobe.module.analytics>]: GetSharedState - Shared State for com.adobe.module.identity couldn't be retrieved at the time, will retry later. If this message persists, please make sure you have registered and configured the com.adobe.module.identity extension properly based on the documentation.

Please suggest what needs to make sure in my MobileProperty.

Thanks

Sai
