This script will download all the session material for you if you are a WWDC 2017 attendee OR NOT! You can now simply install WWDC-Downloader as a ruby gem like this:
gem install wwdcdownloader
or
sudo gem install wwdcdownloader
Run the script like this:
wwdcdownloader [<target-dir>]
The script will create a directory called "wwdc2017-assets" (or target-dir
if given) in the directory you run the script from.
That's it. Enjoy and see you next year.
