ios - Undefined symbols for architecture armv7 with static library -

i've been trawling around internet around 3 hours , still haven't managed find fix. i've tried adding library 'quickblox' , needed frameworks , links in frameworks search paths - still continue errors. although it's asked libresolv.dylb, isn't available in ios 9. large amount of errors reasonably similar 1 below:

undefined symbols architecture armv7:   "_xmlcreatepushparserctxt", referenced from:       l002 in quickblox(xmppparser.o)   "_xmlfree", referenced from:       l024 in quickblox(ddxmlnode.o)       l025 in quickblox(ddxmlnode.o)       l075 in quickblox(ddxmlnode.o)       l077 in quickblox(ddxmlnode.o)       l105 in quickblox(ddxmlnode.o)       l003 in quickblox(xmppparser.o) 

i'm wandering main issue - feel though should working!

cheers - seboh.

turns out it's bug in xcode 7 beta. upgrading beta 3 - fix issues.
