title: How to register Settings.bundle keys on shared defaults
body: <p>I am trying to link settings properties with the app. I managed to do it using <code>standardUserDefaults</code>. The problem is that my app have and extension and I need to use Shared Defaults with a SuiteName. </p>
  
  <p>Although I use the same register method on shared defaults, the properties changed in the settings bundle are not updated in the app. </p>
  
  <p>I want to ask first if this is possible. And if so, how is the way to achieve it. </p>
