Not getting all data from API - ios

Question

let APIUrl = NSURL(string:"https://api.openweathermap.org/data/2.5/weather?lat=(currentLocation.coordinate.latitude)&lon=(currentLocation.coordinate.longitude)&appid=e7b2054dc37b1f464d912c00dd309595&units=Metric%22")
let request = URLRequest(url:APIUrl! as URL)
let dataTask = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error ?? "Error is empty.")
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse ?? "HTTP response is empty.")
}
guard let responseData = data else {
print("Error: did not receive data")
return
}
do {
let weatherData = try JSONDecoder().decode(MyWeather.self, from: responseData)
let ggtemp = weatherData.main?.temp
print(ggtemp!, "THIS IS THE TEMP")
DispatchQueue.main.async {
self.tempDisplay.text = String(format: "%.1f", ggtemp!)
}
} catch {
print("error parsing response from POST on /todos")
return
}
})
dataTask.resume()
}
I want to get the temperature of my current Location.
Here is what I get when app runs:
<NSHTTPURLResponse: 0x28322fbe0> { URL: https://api.openweathermap.org/data/2.5/weather?lat=(currentLocation.coordinate.latitude)&lon=(currentLocation.coordinate.longitude)&appid=e7b2054dc37b1f464d912c00dd309595&units=Metric%22 } { Status Code: 400, Headers {
"Access-Control-Allow-Credentials" = (
true
);
"Access-Control-Allow-Methods" = (
"GET, POST"
);
"Access-Control-Allow-Origin" = (
"*"
);
Connection = (
"keep-alive"
);
"Content-Length" = (
78
);
"Content-Type" = (
"application/json; charset=utf-8"
);
Date = (

);
Server = (
openresty
);
"X-Cache-Key" = (
"/data/2.5/weather?lat=&lon=&units=Metric%22"
);
} }
error parsing response from POST on /todos
Any ideas on how to get the temp from this API?
Here is my struct code:
struct Coordinate : Decodable {
let lat, lon : Double?
}
struct Weather : Decodable {
var id : Int?
var main, myDescription, icon : String?
enum CodingKeys : String, CodingKey {
case id = "id"
case main = "main"
case icon = "icon"
case myDescription = "description"
}
}
struct Sys : Decodable {
let type, id : Int?
let sunrise, sunset : Date?
let message : Double?
let country : String?
}
struct Main : Decodable {
let temp : Double?
}
struct MyWeather : Decodable {
let coord : Coordinate?
let cod, visibility, id : Int?
let name : String?
let base : String?
let weather : [Weather]?
let sys : Sys?
let main : Main?
let dt : Date?
}

I check your api in postman get this response
{
"coord": {
"lon": 90.36,
"lat": 23.79
},
"weather": [
{
"id": 721,
"main": "Haze",
"description": "haze",
"icon": "50d"
}
],
"base": "stations",
"main": {
"temp": 304.15,
"pressure": 1013,
"humidity": 62,
"temp_min": 304.15,
"temp_max": 304.15
},
"visibility": 3000,
"wind": {
"speed": 4.1,
"deg": 330
},
"clouds": {
"all": 20
},
"dt": 1540182600,
"sys": {
"type": 1,
"id": 7879,
"message": 0.0056,
"country": "BD",
"sunrise": 1540166342,
"sunset": 1540207601
},
"id": 1337178,
"name": "Dhaka District",
"cod": 200
}
this is your full API response model class used this code
struct MyWeather : Decodable {
let coord : Coordinate?
let weather : [Weather]?
let base : String?
let main : Main?
let visibility: Int?
let wind : Wind?
let clouds : Clouds?
let dt : Date?
let sys : Sys?
let id : Int?
let name : String?
let cod : Int?
}
struct Coordinate : Decodable {
let lat : Double?
let lon : Double?
}
struct Weather : Decodable {
var id : Int?
var main, myDescription, icon : String?
enum CodingKeys : String, CodingKey {
case id = "id"
case main = "main"
case icon = "icon"
case myDescription = "description"
}
}
struct Main : Decodable {
let temp : Double?
let pressure : Int?
let humidity : Int?
let temp_min : Double?
let temp_max : Double?
}
struct Wind : Decodable {
let speed : Double?
let deg : Int?
}
struct Clouds: Decodable {
let all : Int?
}
struct Sys : Decodable {
let type : Int?
let id : Int?
let message : Double?
let country : String?
let sunrise : Date?
let sunset : Date?
}

Your code is parsing the data. However, I noticed at the end of your URL units=Metric%22 which should just be units=Metric. Also, your lat and lon will be incorrect. lat=(currentLocation.coordinate.latitude) should be lat=\(currentLocation.coordinate.latitude) and same for lon.
