title: XCode can't find main.m file after rename project
body: <p>I have strange but probably quite simple problem with rename Xcode project. I did everything like this guy show on this video 
  <a href="https://www.youtube.com/watch?v=jRnVjtNLLLk" rel="nofollow noreferrer">https://www.youtube.com/watch?v=jRnVjtNLLLk</a></p>
  
  <p>So I change project name in identity and type, change schema name, change app folder name and I change location of files to new folder. I also change properties in build settings and everything seems to look ok, but I have this error when I try to build app:</p>
  
  <blockquote>
    <p>Apple LLVM 8.0 </p>
    
    <p>'myPathToProject/oldProjectName/newProjectName/main.m'Error clang: error: no such file or directory:</p>
  </blockquote>
  
  <p>This directory don't exist. 
  I don't know why xcode looking for main.m file in this no existing directory and I don't know how and where to add a correct path to the main.m Any ideas?</p>
