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 this problem by setting that:

ARCHS = armv7 armv7s

VALID_ARCHS = armv6 armv7 armv7s arm64
