How to: bulk convert SVG to PDF on macOS

Simple and Easy. Just 3 Steps!

Recently, I imported a number of SVG images to Xcode for my app development but the files were not displaying correctly. Therefore, I tried to convert one of them via an online SVG-to-PDF converter tool which made the thing works again. However, the online converter cannot accept too many files at the same time :(

When I searched the solution on the Internet, I found a free tool on Github that can solve this problem smoothly and I would like to share the use of this tool with you.
