Hi! guys!
For the weather app project I’d like to switch the background image according to the fetched weather data (“partly cloudy”, “sunny”…etc…); i want to set up a function that does all that, and that seems fairly easy;
The thing is: i do not know all the possible weather descriptions i could be possibly getting from the API…is there a way to retrieve that info in their docs? If so, i could then set up an array and use it in my function;
Thank you!
The API should have documentation explaining all the possible outcomes and codes, post the API you are using, maybe we can help you out 
EDIT: Didn’t realize your API was named Dark Sky. This is the data you were looking for in the documentation:
icon optional
A machine-readable text summary of this data point, suitable for selecting an icon for display. If defined, this property will have one of the following values: clear-day, clear-night, rain, snow, sleet, wind, fog, cloudy, partly-cloudy-day, or partly-cloudy-night. (Developers should ensure that a sensible default is defined, as additional values, such as hail, thunderstorm, or tornado, may be defined in the future.)

perfect, that would be it! thanks so much
