When try to build IPA file for Testflight there was just a zero xarchive file and it didn't appear in the Organizer panel in Xcode 4.6.3. I checked the libraries for Skip install...but no solution.
It worked earlier and worked with all other apps, so I don't think that there could be any settings problem in the Xcode. I have two targets a full and lite version. There was no any warning or error log just didn't happen anything even the archiving runs without problem.
Read and tried all the hectic answer in this topic but no solution.
