Does LLDB have convenience variables ($var)?

Question

Does LLDB have convenience variables? If so, how do I use them? If not, is there anything similar that I can use?

Answer 1

Just use the form:

(lldb) expr var

From their tutorial:

(lldb) expr self
$0 = (SKTGraphicView *) 0x0000000100135430
(lldb) expr self = 0x00
$1 = (SKTGraphicView *) 0x0000000000000000

You can also call functions:

(lldb) expr (int) printf ("I have a pointer 0x%llx.\n", self)
$2 = (int) 22
I have a pointer 0x0.
(lldb) expr self = $0
$4 = (SKTGraphicView *) 0x0000000100135430
