Save Alamofire Result as Variable? - ios

Question

I've been trying to find out how to save a part of a JSON response from Alamofire as a variable to make an if statement and can't seem to find how to do it.
I made a piece of code to use as an example for the question which consists of the following:
import UIKit
import Alamofire
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
Alamofire.request("http://api.openweathermap.org/data/2.5/weather?q=London,uk&appid=44143256ee15e9c3f521ca062463dd8d").responseJSON { response in
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
}
}
I get the following response from the API request:
JSON: {
base = stations;
clouds = {
all = 0;
};
cod = 200;
coord = {
lat = "51.51";
lon = "-0.13";
};
dt = 1485031800;
id = 2643743;
main = {
humidity = 83;
pressure = 1026;
temp = "270.54";
"temp_max" = "273.15";
"temp_min" = "267.15";
};
name = London;
sys = {
country = GB;
id = 5091;
message = "0.0038";
sunrise = 1484985141;
sunset = 1485016345;
type = 1;
};
visibility = 7000;
weather = (
{
description = haze;
icon = 50n;
id = 721;
main = Haze;
}
);
wind = {
speed = 1;
};
}
From this JSON response I would like to save the weather description so I could use the following statement:
if var currentWeather = sunny {
return "Nice day!"
} else {
return "Uh-Oh, keep warm!"
}
If anyone could help me with this I would greatly appreciate it! If I have to use SwiftyJSON to make it easier that's fine I've just been struggling with this for a while and need to figure it out!

Answer 1

You can parse your result following the printout of your JSON response:
guard let JSON = response.result.value as? [String:Any],
let weather = JSON["weather"] as? [[String:Any]] else {
print("Could not parse weather values")
return
}
for element in weather {
if let description = element["description"] as? String {
print(description)
}
}
If you wanted to save the result, or do something based on a certain result as you described, you could insert something else instead of just print(description) like:
if description == "sunny" {
//do something
}
Let me know if this makes sense. Keep in mind that ( and ) in the Xcode console means "Array".
