Hello. I am the founder of the design school "Science of Design" in Russia and we produce many materials for designers in free access. This summer we redrawn iOS 13 ui kit for Figma. In our country we have a very big problem with visual quality of applications and the problem is that designers do not know the rules for creating applications on iOS. That's why we decided to make HIG more accessible and translate it into Russian.
The most important question is whether we can translate it and put it on the network? It will be distributed free of charge.
And the second question is how to find out that HIG has been changed so that we can make changes in our translation.
Keeping in mind that you are mainly talking to other devs here, I suggest you visit the main HIG page, then read the TOU link at the bottom.
If there are enhancements you'd like to see, feel free to use the report bugs link below to make a request against the docs.
