I am working on an app that pulls data from weatherKit, including the conditionCode property, the content of which is displayed to the user. I wish to localize the data pulled from weatherKit but when pulling data from: weatherkit.apple.com/api/v1/weather/de/{latitude}/{longitude} The conditionCode and other strings is in english. Same is true if the language parameter is set to es, ja or something else. Am I doing something wrong or is localization yet to be supported in weatherKit? I can't find any documentation on this.

One of the possible values of the forecast property conditionCode is sleet. But according to wikipedia this term refers to multiple, quite different weather phenomena. Some harmless and other potentially hazardous. What type of weather does sleet refer to in the weatherKit API?
