Linker command failed with exit code 1 error in Xcode project

Question

I was working on my project and suddenly after editing the code and compiling gave this error:

ld: warning: directory not found for option \'-
L/Use

Answer 1

As I said the problem wasn't the code but some settings. So what I did was copying the code from my friends' Mac (it was working fine), and installed a fresh copy of the project to my Mac. It worked.
