Is Crowdin supposed to be supporting the "shouldTranslate": false attribute in an xcstrings file? I just modified an xcstrings file to include these and updated the file on the Crowdin website, but these strings are still visible to translators.
FWIW, I haven’t found any documentation of what the xcstrings schema looks like, but you can add this UI in XCode by right- or ctrl- clicking on a string in an xcstrings file and choosing Mark as "Don't Translate".
There is nothing on that page about the shouldTranslate attribute. If you don’t support it, then please consider this a request for this feature: if "shouldTranslate: false is present, the string should be hidden from translators on Crowdin.
