undefined symbol for arm64 _kCFStreamSSLAllowsExpiredCertificates in CommLibiOS.a(RTMPClient.o

Solved : I just added CFNetwork and Security frameworks

I just upgraded to Xcode 7.3 on El Capitan and it seems to be something wrong with the constants in CommLibiOs
Undefined symbols for architecture arm64:
“_kCFStreamSSLAllowsExpiredCertificates”, referenced from:
-[RTMPClient createSocket:andPort:] in CommLibiOS.a(RTMPClient.o)
there are some other _kCFStream… constants errors
Anyone else experiencing this?
Thank you

Please update the latest Backendless SDK from CocoaPods (3.0.23) or from github (CommLibiOS and backendless).
