Xcode 8 linking error help

Hi everyone,this is the linking error that I get when trying to build an app on Xcode 8 (Unity version -> 5.5.2f1) ...so far I tried to fix it by :

1)Changing architectures(armv7 and arm64 and standard architectures) 2)Changing "Build active architecture only" to no 3)Changing "Dead code stripping" to no 4)Adding $(inherited) to "Other Linker Flags" 5)Adding "Security" and "SystemConfiguration" Frameworks to Build Phases 6)Enabling "Symlink Unity Libraries" in Unity Player Setting 7)Disabling "bitcode" and enabling "Preserve Private External Symbols"

Nothing worked ...
