 When developing an application with multiple targets (such as **Stage**, **Live**, **Master**, etc.), Here are the necessary steps and configurations:
 
 ### 1. Service Extensions
-    - Each target should have its own service extension to handle notifications and functionalities independently.
-    - Add a new target for each service extension in your Xcode project.
-    - Ensure that each service extension is configured to handle notifications specific to its environment.

 ### 2. App Groups
-    - Set up separate App Groups for each target to enable communication between your app and its service extensions.
-    - Create distinct App Groups for Stage, Live, and Master targets in your project settings.
-    - Update the entitlements files for each target to include the corresponding App Group.
-    - Ensure that the logic in your app and extensions uses the correct App Group for data storage and sharing.
