How to count the lines of an Xcode project

The easiest way is to open the terminal app and navigate to the Xcode project and paste the following line:

find . "(" -name "*.m" -or -name "*.h" -or -name "*.mm" -or -name "*.cpp" ")" -print0 | xargs -0 wc -l

 You will get an result similar like this one:
