Sniffer is based on NetworkExtension framework and provides system level's Network Session Sniffing.
Before running, use Carthage to integrate CocoaAsyncSocket & ZPTCPIPStack.
If you installed carthage, just run this command.
carthage update
Then, add the extension and framework's scheme.
there is a problem with directly integrating ZPTCPIPStack into project using Carthage, so I must refer the files to the project's inner framework. if you just run this demo, well, no problem. but if you want to modify file or file's organisation, you must know what you are doing.
Now, this demo just implement HTTP & HTTPS & TCP(Except HTTP & HTTPS) Proxy.
