Unable to parse data from API Request Swift - ios

Question

I am currently working on learning Swift and I tried to parse data from an open API working with Codable. I followed some tutorials and ended with non data fetched.
Codable:
import Foundation
struct currentWeather: Codable {
var temperature: Double
var time: String
var weathercode: Double
var winddirection: Double
var windspeed: Double
}
struct Weather: Codable {
var elevation: Double
var latitude: Double
var longitude: Double
var timezone: String
var timezone_abbreviation: String
var utc_offset_seconds: Int
var generationtime_ms: Double
var currentweather: currentWeather
}
RequestManager:
import Foundation
class RequestManager {
static let url = URL(string: "https://api.open-meteo.com/v1/forecast? latitude=42.70&longitude=23.32&current_weather=true")
static var temperature: Double = 0.0
class func getWeatherData() {
var request = URLRequest(url: url!)
request.httpMethod = "GET"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let task = URLSession.shared.dataTask(with: request, completionHandler: {
(data, response, error) in
guard let weather = try? JSONDecoder().decode(Weather.self, from: data!) else {
print("Cannot parse data!")
return
}
RequestManager.temperature = weather.currentweather.temperature
})
task.resume()
}
}

Answer 1

First things first, url has blanks, you should update it like that.
static let url = URL(string: "https://api.open-meteo.com/v1/forecast?latitude=42.70&longitude=23.32&current_weather=true")
Further, you need to update currentweather property in the Weather struct. The name convention is different in the response. So you can use this struct instead. On the other hand, you may check CodingKeys for better property names.
struct Weather: Codable {
var elevation: Double
var latitude: Double
var longitude: Double
var timezone: String
var timezone_abbreviation: String
var utc_offset_seconds: Int
var generationtime_ms: Double
var current_weather: currentWeather
}
