thank you for your work and your approach to even get this work done! :)

And yes, currently you have almost no chance to port a current interface 
to GNUstep. I installed three virtual macOS machines to be able to use 
Xcode/IB to backport a current xib to a GNUstep compatible nib/Xcode 
4-xib (which works quite well), but you have to delete many items of the 
interface to be able to use it with Gorm/GNUstep.

That said if would be great of course to even have the xib support of 
Gorm updated for making porting and cross platform development easier.

Maybe some sort of dev survey would be nice? Just to get an idea wich 
classes are considered most needed so you know there is good cause to 
start with specific ones?

That said highest priority for me would be to have tested API 
compatibility concerning the existing classes (same for base). Writing a 
new app or porting from GNUstep to Cocoa is much easier if we’d have a 
solid base there, I think.

As a first project I just updated DictionaryReader.app to make it work 
on Cocoa. It does, but the implementation/use of NSUInteger is probably 
be different for Cocoa and GNUstep as my changes on this class do not 
work using GNUstep: 
https://github.com/Letterus/DictionaryReader/commit/368b39fa1bd81bf7482860d6b85a537d235533d8#diff-3dc9afee5b822cb486003ac0d8405667

I’m currently missing the knowledge to figure out what/where the cause 
for the issue exactly lays, though.

Keep up your great work
Johannes
