Inspired by qiaoxueshi/WWDC2015Video_Subtitle, ohoachuck/wwdc-downloader, and @onevcat's videos. Thanks for their inspiration and efforts. 👏


WWDCHelper is a command line tool on macOS for you to get WWDC info easily. Now you can get download links of SD/HD video & PDF, and download subtitles in English, Janpanese (only WWDC 2018 & 2019), and even Simplified Chinese directly by it.

You can also download subtitles at the releases page.


Although I have written in Swift for years, I still have a lot to learn about Swift. And to be honest, CLI (Command Line Interface) is not familiar for me. So this program is not perfect, even a little wired. So you can issue me if you have any questions, advices or find some bugs . I will be very appreciated for your help. ❤️



You should have Swift Package Manager installed or latest Xcode installed with command line tools in your macOS.

> git clone
> cd WWDCHelper
> ./


WWDCHelper -h
