An App Group allows different applications (or an application and its extensions) to access a shared file storage location. App Groups can be used for data like:
Configure an App Group
The shared location is configured using an App Group, which is configured in the Certificates, Identifiers & Profiles section on iOS Dev Center. This value must also be referenced in each project's Entitlements.plist.
The app group will have an identifier, which is typically your
Bundle ID with a
group. prefix. For example, we could use
the Bundle ID
com.xamarin.WatchSettings and the app group
As well as configuring the provisioning profile, Enable App Groups in the Entitlements.plist and enter the ID you've chosen:
Ensure you configure the App Group correctly in your deployment provisioning.
