Do you use tools for intercepting and analyzing network traffic?

Yes, tools such as Wireshark, tcpdump, or Charles Proxy are often used for intercepting and analyzing network traffic.

For example, Wireshark allows capturing packets, filtering them by various parameters, and analyzing protocols at a low level. This is useful for debugging network issues, performance analysis, or security.

In iOS development, Charles Proxy is often used to intercept HTTP/HTTPS traffic of a mobile application, helping to verify server requests, headers, request and response bodies.

Example of using Charles Proxy:

• Set up a proxy server on a computer.
• Connect the iOS device to the same network.
• In the Wi-Fi settings of the device, specify the proxy with the computer's IP and the Charles port.
• In Charles, you can see all HTTP/HTTPS traffic of the application.

Thus, these tools help to gain a deeper understanding of what happens in the application's network interactions.
