Cocoa packet analyzer is a native Mac OS ximplementation of a network protocol analyzer and packet sniffer. CPA supportsthe industry-standard pcap packet capture format for reading, capturing andwriting packet trace files.
This is a simple packet capture tool I found on the network when I started my iPhone. It is enough for TCP communication.

A very professional packet capture and analysis tool. It is an open-source and cross-platform tool that supports various protocols, HTTP and TCP. It is a very good analysis tool. I think it is very useful.

It's a pity that the HTTP protocol is a paid Master. It's good to find a cracked version.

Web development tools are not suitable for mobile phone development and have never been used. The Firefox plug-in httpfox should also be.
Tcpdump
What is the most powerful? Of course, it is a command line. It works with SSH and performs operations directly on the mobile phone. The real environment test is very easy to use. Unfortunately, the threshold for use is a little high, here we will not detail it here.
