ios - Xcode Beta 6.3 magically delegates tasks to other threads? -

we've came onto strange bug in our project (i hope it's bug not our fault). let's jump straight problem.

our application storyboard based, of course of study connects external api etc. we've faced unusual thing regular implementation of prepareforsegue: , things related segues automagically delegates things other threads. little illustration - when nslog(@"sample log") in viewdidload doesn't fired when should gets called in random time that's why guessed might delegated other-than-main thread. firstly thought networking layer may cause because of blocks , when set direc logs application called in random time! we've tried check thread in debugger , shows thet happens in main thread. strange, right?

anyway, colleagues check against different versions of xcode because on machine there bothe 6.2 , 6.3 beta. when compile on computer 6.3 installed works properly! possible 6.3 beta introduces changes handles segues differently previous versions? or maybe should start seeking troubles oher place?
