Yes.

Depending on which configuration options you preferred when  
installing GNUstep, you actually use Apple's Foundation framework.  
Short of some possible bugs, they are 100% interchangeable (and  
GNUstep's Foundation ist pretty much complete).

(joke)Against Apple's Foundation on monday, tuesday and wednesday.  
Against GNUstep's on the other days ;-) (/joke)

Yes.

Does the linker find the framework? Have you investigated the  
framework with nm / otool?
