Chisel is a collection of LLDB commands designed to assist you in the process of debugging iOS apps. All of the commands provided by Chisel come with verbose help. Be sure to read it when in doubt! You can add local, custom commands. There's also builtin support to make it super easy to specify the arguments and options that a command takes. See the border and pinvocation commands for example use. Developing commands, whether for local use or contributing to Chisel directly, both follow the same workflow. You can also inspect a specific command by passing its name as an argument to the help command (as with all other LLDB commands). There are many commands with compatibility with iOS/Mac. For a comprehensive overview of LLDB, and how Chisel complements it, read Ari Grant's Dancing in the Debugger, A Waltz with LLDB in issue 19 of objc.io.
