I want to know whether full disk encryption is enabled on the iPhone, and what I should do with code

I downloaded an app about PacketTunnelProvider from github, and changed the bundleid of the app. The program can run and the function is easy to use. But when I deleted the target of the PacketTunnel and tried to create a new target of the PacketTunnel myself, I found that the code was not executed, and the bundleid ID was still used, which was applied from the developer center. I use xcode 13.2.1. I want to ask you to tell me why the new target is difficult to use, but the original one is. I guarantee that the bundleid is available. I've tried many times, but I can't realize it. What configurations are missing

I'm sorry, my English is poor, but I really need your help, thank you I would like to ask whether the framework I made can include the functions of the APP Extension? I'm a novice to the App Extension I have developed an app for vpn traffic interception, which uses the Network Extension and can currently achieve the functions I want However, I also need to provide an sdk for others to use, so I need to include the relevant functions of the Network Extension in the sdk. I wonder if it can be implemented?
