po            -- ('expression -O  -- ')  Evaluate an expression (ObjC++ or Swift)
                 in the current program context, using user defined variables and

repl          -- ('expression -r  -- ')  Evaluate an expression (ObjC++ or Swift)

# Chisel

binside       -- Set a breakpoint for a relative address within the framework/library that's
                 currently running. This does the work of finding the offset for the
                 framework/library and sliding your address accordingly.
bmessage      -- Set a breakpoint for a selector on a class, even if the class itself doesn't
                 override that selector. It walks the hierarchy until it finds a class that does
                 implement the selector and sets a conditional breakpoint there.
                 Examples: "-[MyView setFrame:]", "+[MyView awesomeClassMethod]" or "-[0xabcd1234 setFrame:]"
