Hi Tommy,
There is a list of current API compatibility somewhere, but I can't
find it at the moment. A good few rules of thumb are:
- Try to stick to Foundation and AppKit. A few other frameworks, like
AddressBook, also work, but are external to the core GNUstep
distribution.
- Anything that says 'OS X 10.0 or later' in Apple's documentation is
likely to work. Anything that says 10.5 or later probably won't
work. For 10.1 to 10.4, the probability gradually drops. As such,
it's best to try to stick to 10.0 stuff and test other things on
GNUstep before relying on them.
- Reading nib files on GNUstep is still somewhat hit and miss. Some
things work perfectly, some fail weirdly. If you are encountering
strange bugs, try redrawing your nibs in gorm.
You may also find some slight inconsistencies between GNUstep and
Cocoa. For example, the NSFileManager method for creating a directory
on Cocoa requires the parent directory to exist, but on GNUstep will
create all intervening directories if they are missing (Leopard
introduces a new method for doing this).

I'm wondering if there is any document available that describes the
differences between
the Cocoa API on Mac OS X, and the Gnu-step API. If possible, I want
to write my code
so that it is easily portable to other operating systems.
