I really don't get it - what problem! This is part of my frustration
with some of the comments on this thread
A Cocoa app can easily host a Carbon view - there is ample support in
there for doing that.
A Carbon app (which is what ALL of the major hosting apps are written
in) cannot easily host a Cocoa view.
So - if we make it easy for you to have Cocoa Views for AudioUnits who
is going to use them? Or is it more important for you that your life is
easy and comfortable, but no-one can use your audio units?
That is the quandary, that is why it is the way it is now. As this
situation is fixed or changes we will do our part.

O.K.
BUT
One thing that I think we did well with AUs was to distinguish
between the model and the view of the DSP. If Cocoa is good for UI
and your preferred UI choice, then it is certainly easier for a Cocoa
based hosts to host a Carbon UI than vice versa.
I agree with this, including the model-view separation. But, it only
helps the host developer.
All of the strengths that have been discussed about Cocoa relate to
the UI capabilities - and if/when we do do work in this area it will
be in that aspect of the AU - its view.
I don't see us changing any of the implementation and container of
the DSP code (the AU proper) to be anything but C/C++ anytime soon.
However, that doesn't mean that's the only way that the API for users
of AUs or other CoreAudio APIs will be published.
Cocoa has advantages other than UI. The reason I think that we are
mainly talking about UI is that this is the only thing the Cocoa
people can't do anything about.
I would like to see the SDK in Objective C. If you choose not to
provide this, we can write our own. Just as people have already
written Objective C API's for the HAL and some of the AU.
When It comes to the AU UI, we can't fix our problem.
Thanks for the reply.

It was gently pointed out to me in a private email, that my
arguments about the age of the Carbon library where wrong (and
silly). I think that it is important to correct myself on this
point. The design and implementation of Cocoa is nearly as old as
Carbon. Cocoa is actually a mature and well tested library. My
point should really have been that Cocoa is the best UI development
platform out there (anywhere) and Carbon isn't.
Again, thanks for all the feedback on this. I really would like some
from someone at Apple, even if it is just to tell me I'm out of
luck. If Apple isn't going to be giving us Cocoa based AU's any
time soon then I will set up my own plugin format for the app I'm
working on. I will lose all of the nice stuff from AU graphs and I
will have to build adaptors between AU's and the other plugins, but
I think it will be well worth it.
