The real problem is that you're trying to define this chimera class in the same header. If you split it into two separate headers, each nib only needs to know about the header that applies to it. Target Membership will do the rest, since the right nib and the right header are part of the same target and there's no crosstalk to the other target.
Since IB can't 'see' #ifdef in your header, you just can't do it in the same header. Neither is there any reason to. Having done that, there's probably no merit in trying to merge the code either, just have two separate objects, get rid of all the #ifdefs and use Target Membership to select the right one for the job.

Just make the outlets type id and they can point to anything.
