access json with the rapidapi provided nsurlsession

Question

I'm trying to use this weather api https://rapidapi.com/interzoid/api/us-weather-by-zip-code/endpoints in my xcode project with swift. They provide me with the code

import Foundation

let headers = [
    "x-rapidapi-host": "us-weather-by-zip-code.p.rapidapi.com",
    "x-rapidapi-key": "my api key"
]

let request = NSMutableURLRequest(url: NSURL(string: "https://us-weather-by-zip-code.p.rapidapi.com/getweatherzipcode?zip=11214")! as URL,
                                        cachePolicy: .useProtocolCachePolicy,
                                    timeoutInterval: 10.0)
request.httpMethod = "GET"
request.allHTTPHeaderFields = headers

let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
    if (error != nil) {
        print(error)
    } else {
        let httpResponse = response as? HTTPURLResponse
        print(httpResponse)
    }
})

dataTask.resume()

After running it I get the response headers but I wish to get the reponse body which is the json. I'm still pretty new to this and hope you can help.

You need to parse the response. The JSONSerialization class method jsonObject(with:options:) returns a value of type Any and throws an error if the data couldn’t be parsed.

let json = try? JSONSerialization.jsonObject(with: data, options: [])
