Accessing weather information for next 3 days, not just current

in the weather app, we are accessing the current weather data using the keyword "currently" - if I instead wanted to access the weather data for the next three days how can I go about accessing the data from the "daily" dictionary? It looks like there is an embedded dictionary inside?

Hi Steve, could we get a code sample on how to access a value inside the daily dictionary? The JSON data prints below (i simplified it a bit):

{
    currently =     {
        apparentTemperature = "51.21";
    };
    daily =     {
        data =         (
                        {
                apparentTemperatureMax = "51

I'm able to access the currently dictionary as instructed in the video with:

let currentWeather = weatherDictionary["currently"] as NSDictionary

        temperature = currentWeather["temperature"] as Int

But then, how would I access the daily data? I've tried below with no luck. I thought the ( would mark an array, and so I'd be accessing the value in the daily key-value pair, and then accessing an array of the information inside that value. Is that incorrect?

let dailyWeather = weatherDictionary["daily"] as NSDictionary

        temperature = currentWeather["data"][0] as Int

Yes, the weather data is presented in the same (roughly) format for currently, minutely, hourly and daily.

The one's that aren't currently have a Unix timestamp, so you'll need to add that to your dictionary access.

You can access them the same way but you may want to add a tabbed View to make navigation more simple.

Let me know if I can help!

Steve.

Hi Christopher,

There's a whole course dedicated to the subject.

I'll find you a link ... or check out my Github repo, if you want.

Steve.
