[XCode] To Change The Project Name Safety

If we change project.pbxproj file, it could be something wrong.

so I've found a solution on internet.

1. Close the project in Xcode
2. Duplicate the project directory in the Finder by pressing Command-D.
3. Rename the folder
4. Open the folder and rename the “.xcodeproject” file
5. Delete the “Build” sub folder, if there is one
6. Open the renamed .xcodeproject file
7. On the left in the “Groups&Files” list, expand the “Targets” group, double click on the target that still has your old project filename. Rename it under the “General”-tab in the window that opens.
8. Select “Clean all targets” from the “Build” menu, keep the boxes checked, and click “Clean”.
9. Build and run your project.

For me, it was perfect solution.
How about you ?
