Yes but I’m not familiar with the translation management systems yet, I added Dutch manually through Xcode’s own translation thing
The new hotness is the String Catalog .xcstrings format that the new Xcode version supports, rather than the old .strings and .stringsdict formats. Crowdin seems to be a reasonable translation management system option that support the new file format. Nos, Amethyst, and Snort use Crowdin and I want to move Damus to it. They support open source projects.
