Rename Xcode Project

1.Rename project from Xcode

2.Rename scheme

• Most sites tell you only two steps avobe, but that's not enough to rename evrything. Since the original project name also exsists in .phxproj file and .xcuserstate file, you cannot modify these files from Xcode.
• To solve the problem, you can use grep command.

3.Go to your project directory

4.List all lines containing the original project name from the current directory
