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

"The OPN [Debug] target overrides the OTHER_LDFLAGS build setting". This was the main issue. After adding $(inherited) in new line in other linker flags solved my issue.
