Compiling sources in Xcode has wrong path

I recently renamed my Xcode app and did all the changes needed for the Xcode settings. I renamed the folders manually. But now, when I run the application, the build fails. The error I am getting is not a file found by clang. At the build stages, the compilation source specifies the path to the file "New_project_Name / Old_project_Name / New_project_Name / file.m", whereas it should be "New_project_Name / New_project_Name / file.m"

I have searched many different solutions / workarounds and no one has helped so far.
