iOS - Reading same presets and resources in AUv3 as in standalone

…making an AUv3 that also runs standalone, have problems with sharing presets between auv3 and standalone

  1. I have disabled “add duplicated resources folder to app extension”
  2. I have enabled “app groups capability”
  3. I’ve set “app group id” to group.
  4. enabled “Enabled File Sharing”

Now I want to use the special shared folder File::userDocumentsDirectory
I copy all resources (presets and IR’s) there once.
however this folder is only readable from the standalone app…

Is there a solid way to arrange this? Ideally I should be able use the shared userDocumentsDirectory ( which is visible on a connected mac ), for both the standalone and auv3.
