Undefined symbols for architecture arm64

Question

I am getting a Apple Mach-O Linker Error everytime I import a file from CocoaPods.

Undefined symbols for architecture arm64:
  \"_OBJC_CLASS_$_FBSession\", r         


        

Answer 1

I solved it by setting valid archs to armv7 armv7s and setting build active architectures only to YES in release and then doing a new "pod install" from the command line
