Debugging entitlement custom library

Actually the problem is that when I build the viewer for enterprise distribution, I can't debug it, but the application works fine I can see all the folios.

But when I build it with a Developer Certificate, I can debug it in Safari but the library is empty, in fact if I type adobeDPS.libraryService.folioMap.internal is empty.

nothing change between the two apps, only the first one is built for enterprise distribution, the second is built for development distribution.

I can see both asking my server for entitlement with se same parameters
