Yesterday I received a notice from an attorney representing Apple, informing me that this was not actually allowed under the terms of the Xcode license agreement, specifically section 2.12:
The system-provided images owned by Apple and documented as such in Apple's Human Interface Guidelines for iOS, watchOS, tvOS, and/or macOS (“System-Provided Images”) are licensed to You solely for the purpose of developing Applications for Apple-branded products that run on the system for which the image was provided.
I definitely didn't realize this project would violate those terms, so I've happily removed the icon assets from sfsymbols.com and the associated GitHub page. As far as I understand, the site should be able to stay up, though no symbol images means it's not very useful, so I'll probably end up decomissioning it next year when the domain expires.
Everything's always governed by a license, and I don't want to discount the great work of the folks who designed these icons. I do hope that in the future Apple will provide an interface for browsing the symbols that's not a Mac app, so that folks on non-Mac platforms (especially those who might work with iOS developers but aren't developers themselves) will be able to browse as well.
Thanks to the ~2,300 unique users who visited the site since it launched, and those who tweeted about it! It was a fun little project and I learned a fair bit about React building it. I hope it was helpful 👍
