For the new library request issue, please make sure it's not a personal project, we have a basic requirement for the popularity, like 200 stars on GitHub or 800 downloads/month on npm registry.

The new library must have at least one officially public accessible repository and open source license.

Стоит ли мне как пользователю Мака беспокоиться о чем-то?
