How to register Settings.bundle keys on shared defaults

Question

I am trying to link settings properties with the app. I managed to do it using standardUserDefaults. The problem is that my app have and extension and I need to use Shared Defaults with a SuiteName.

Although I use the same register method on shared defaults, the properties changed in the settings bundle are not updated in the app.

I want to ask first if this is possible. And if so, how is the way to achieve it.

Add the ApplicationGroupContainerIdentifier key to the Root.plist file of your Settings-Watch bundle.
