How to force Xcode to relink

Question

When I update a source file (not a header) in Xcode in one library, Xcode doesn't seem to know when to relink with that library.

Is there a way to force xcode to relink without having to clean or modify a header file?

Answer 1

Correct me if I am wrong, but i believe that if you drop the latest source file in the same location and overright the previous version of the file. Xcode will pick the latest source file
