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

You need to just remove arm64 from Valid Architecture and set NO to Active Architecture Only . Now just Clean, Build and Run. You will not see this error again.
