Sorry, that was a rather bald
statement, wasn't it? Let me try and explain. Debugging is often a
matter of context. Depending on the complexity of the program and the
nature of the bug, it can often take a while to get the program to the point of
failure. The ability to fix the bug *there and then*, and the ability
to text that fix (and maybe fix it again, if you got it wrong) can be hugely
productive. It also avoids losing concentration while waiting the the
build to complete and then getting the program back to the point of
failure. But I don't think I can sell this to someone who hasn't tried
it. Only when you actually use it in anger do you come to appreciate what
a great time saver it is.
>> The feature has not been removed
When I filed a bug about Fix 'n Continue being broken (7505431 ), I was
told that it is no longer supported and the bug was closed.
I've said
before on this list that the debugging facilities in Xcode fall well short of
what I'm used to. An expressions window that (a) works properly - it
doesn't reflect values that have changed on my setup - and (b) can be
'docked' as a pane in the source editor (rather than floating freely on the
desktop) is the other major gripe. Debugging at the assembler level is
also painful and the debugger UI is sometimes rather flakey, although I
have learned to live with that, most of the time. My own opinion, based on
developing on both the Mac and Windows, is that improvments to the debugger
would boost the productivity of the average Mac programmer a great deal.
My work is cross-platform, and I do as much development and debugging as I can
on Windows before taking it across to the Mac. What does that tell
you? And it's not just a question of what I'm used to. I have been
working on the Mac for over a year and the debugging environment just doesn't
compare. Which is a shame as Xcode is otherwise very nice and the debugger
rather lets it down.
