JSON request is not returning data
0
I'm trying to create a weather application. I followed a tutorial about JSON and Swift 4 Decodable, I followed the tutorial and it worked. The problem is that when I'm trying to put my own URL to make a request, it won't work.
This is my code:
class MainVC: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
let jsonUrlString: String = "https://api.darksky.net/forecast/APIKEY/37.8267,-122.4233"
private func getForecast(){
guard let url = URL(string: jsonUrlString) else { return }
URLSession.shared.dataTask(with: url) { (data, response, err) in
guard let data = data else { return }
do{
let weatherForecast = try JSONDecoder().decode(Weather.self, from: data)
print(weatherForecast)
}catch _ as NSError{
}
}.resume()
}
}
Error Log:
Error Domain=NSCocoaErrorDomain Code=4864 "Expected to decode Array<Any> but found a dictionary instead." UserInfo={NSCodingPath=(
), NSDebugDescription=Expected to decode Array<Any> but found a dictionary instead.}
How can I parse this https://darksky.net/dev/docs#forecast-request ? I only need the few things from the Daily sections but It seems like an array inside an array to me.

It looks like your Weather struct is built up incorrectly. It should looks something like this:
struct DataItem: Codable {
var summary: String
var uvIndex: Int
}
struct Info: Codable {
var summary: String
var icon: String
var data: [DataItem]
}
struct Weather: Codable {
var daily: Info
var hourly: Info
var timezone: String
}
I've left quite a few items out, but this should help you to get started.

Could you please add your code, otherwise we can't help... The problem is in the JSON deserialisation, so that's the code we need to see to know what is wrong with it.

Sorry took me so long to answer, this was the problem, I did had just one struct so I guess it only took the first item from the JSON. Anyway, Thanks again!
