See the pictures:

On the first picture in the library, on the left, are only a fraction of objects that appear in the second picture.
The pictures are of 2 DIFFERENT projects.
If I try to create a new .xib file the problem still persists and only limited objects are available.
Any ideas?
Thats because the first is an iOS project and the second a Mac OS project.
