Personal Use Shadowsocks App for iOS

I'm looking for a basic, user-friendly Shadowsocks app for iOS tailored for personal use. The app should be optimized for high-speed performance, with strong emphasis on privacy and security.

Key Requirements:
- Basic customization: The app should have the essential features of a standard Shadowsocks app, but it doesn’t need to be overly complicated or have advanced features.
Loading the shadow socks servers should be simple by getting the code from json file.
- High-speed performance: The app should be designed to provide fast and reliable connection.
- Privacy and Security: This is a key feature of the app. It should provide a secure connection and protect my privacy while online.
- User-friendly Interface: The app should be easy to navigate and use, even for someone with limited tech knowledge.

Ideal Skills:
- iOS App Development
- Network Security
- User Interface Design
- Knowledge of Shadowsocks protocol

The app should be based on

But instead of adding the servers manually i want to add it automatically by calling the server location from json file.
