ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I'm having Apple Mach-O Linker Error from 1) "_OBJC_CLASS_$_PFLogInViewController", referenced from: 2) "_OBJC_CLASS_$_PFSignUpViewController", referenced from: 3) "_OBJC_CLASS_$_PFUser", referenced from: 4) "_OBJC_CLASS_$_Parse", referenced from: 5) linker command failed with exit code 1 (use -v to see invocation)

Can i know what is Apple Mach-O Linker Error and the way to solve this error ?

It looks like a problem with the Parse library - did you add it manually (instead of using cocoapods)? If yes, you've probably missed something — Antonio
Did you open up the new workspace it made after the pod installed? The original project would probably do this. — Dare
And have you added ParseUI if you're using visual parse components? — Antonio
