Travis, this isn't correct. My RenaissanceX library will automatically
generate user interfaces at run-time that conform to Apple's Human Interface
Guidelines. If you wish, it will also properly format (arrange/size/space)
controls, based on their logical relationships. You can override that
automatic formatting behavior for a single control, a group of controls, or
as much of the UI as you'd like.
Instead of designing your interface in Interface Builder, you write a
textual description of the interface in a markup file. If you can write
HTML, you can write an interface description. The description not only
includes the names of controls, labels, and other attributes, but also
includes information about how the controls are logically and spatially
related, so that the automatic formatting engine can make appropriate
decisions.
Other than the markup file, and including the RenaissanceX framework inside
your application bundle, you create applications just like people using
Interface Builder. You work with the same Cocoa objects. There aren't any
restrictions.
RenaissanceX is based off of Renaissance for GNUstep, modified and extended
to make it work better on the Mac. I'm still working on it, but the current
version is quite usable.

Since xCode is quite accessible, and RenaissanceX removes the need for
Interface Builder, you can program anything that you want in ObjectC.
You might also wish to join the MV-Dev group on Google to talk with other
blind people that are writing software on Macs.

When programming on osx, you'll need to find a combination of tools that
work for you. If you have some vision, then the Xtools will work just fine
for you. If however you're like me, and are not able to see the screen,
then anything other than modifying existing code (or generating interfaces
from code) isn't possible. Apple's interface builder, (the program it uses
to generate the graphical portions of
programs written in objective C) isn't accessible to voiceover users.
You can build programs to be sure, but you can't use Ibuilder to make those
nice aqua interfaces everyone loves so much on the mac. (at least not
without sighted assistance) You can build programs from scratch that have
graphical interfaces, but it requires one heck of a lot of patience,
intimate knowledge of objective C internals, and a whole lot of sample code,
because apple has a habbit of modifying how things are done from release to
release, so something that works in
10.5 may not work in 10.6, and if you aren't using interface builder to
generate your interfaces, you're going to have a lot of trouble making
things work when a new release comes out.
For that reason, I don't even try to generate graphical interfaces using
ibuilder, or apple-provided sample code.
Instead, if I need graphical elements, I'll either use apple script, (if
only a few things are needed) java (since java takes care of layouts for me,
and I don't have to worry about whether they're ligned up or not) or I'll
just create a terminal application, which has no graphics, but can be
wrapped in an apple script or something to make it launch from finder
normally. There's all sorts of things that can be done to make stuff
behave, but using interface builder (for us) isn't one of them.
Xcode itself is fine, you can still edit compile and create code using the
Xcode tools as long as you're not trying to use interface builder to build
an interface from scratch. You can modify existing interfaces (to add
accessibility labels, change types, and the like) but again, developing from
scratch is impossible.
All is not lost though, as mentioned above, there are other options, and of
course, nothing says you need to use Xtools at all, you can use your
favorite development environment (such as emacs) if you're already an
entrenched developer, most of your existing tools can be ported to osx with
little or no changes, and you can continue doing what you do best, making
programs for others to enjoy. It's just the graphical components that will
cause a bit of headache.
