Since I'm new to this, I'm trying out the beginings of a tutorial here on my user page.
There is some interest in using Haskell on the Mac with a real Mac (Aqua) interface. There are a couple of things out there which are mentioned on the Missing tutorials page. My adventures with, or reading about, these left me in need of the missing tutorial, rather than the ability to write one. But that's another topic.
This tutorial doesn't meet the needs of the Missing tutorial page. It is much less ambitious.
It assumes you know something about Xcode, and something about Haskell. Its not an objective-c bridge. But it does seem to provide a simple way to incorporate a Haskell model doing the heavy computation into a Cocoa application.
This is rudimentary, and more work needs to be done, but I decided to put this out before spending a lot of time on polishiing. The section "To do" lists things I can think of to add to this tutorial, some hard, some easy.
