Swift

I have Swift code to call on the Open Weather API.The code works well with any one word city (eg Rome), but balks at a city with more than one word (eg New York).

I have some print statements to show console output at various steps and they all work with a single word input city. The console output shows the expected JSON string.

With a city like New York or Los Angeles, I get the console print of the URL, but no JSON.

I copy and paste the NY console URL string into a browser and the site responds appropriately. Value of myKey redacted.

Output for Paris

URL is: https://api.openweathermap.org/data/2.5/weather?&appid=myKey&units=metric&q=Paris

JSON is:

\"weather\":[{\"id\":701,\"main\":\"Mist\",\"description\":\"mist\",\"icon\":\"50n\"}],\"base\":\"stations\",\"main\":{\"temp\":4.76,\"feels_like\":4.76,\"temp_min\":3.08,\"temp_max\":6.03,\"pressure\":1024,\"humidity\":92},\"visibility\":5000,\"wind\":{\"speed\":1.03,\"deg\":310},\"clouds\":{\"all\":90},\"dt\":1636571558,\"sys\":{\"type\":2,\"id\":2041230,\"country\":\"FR\",\"sunrise\":1636527115,\"sunset\":1636561035},\"timezone\":3600,\"id\":2988507,\"name\":\"Paris\",\"cod\":200}")

extracts of JSON:
CITY is Paris
TEMP IS 4.76
mist

for New York:
https://api.openweathermap.org/data/2.5/weather?&appid=myKey&units=metric&q=New York
No JSON

Any ideas?
Thanks!

What I have tried:

struct WeatherManager {

    

    let weatherURL =  "https://api.openweathermap.org/data/2.5/weather?&appid=myKey&units=metric"


    func fetchWeather (cityName:String) {

        let urlString = ("\(weatherURL)&q=\(cityName)")

        //let urlString = "https://api.openweathermap.org/data/2.5/weather?&appid=myKey&units=metric&q=New York"


        print("**URL*** \(urlString)")

        performRequest(urlString: urlString)

    }

    

    func performRequest(urlString: String) {

            //1.  create the URL? (optional)

        if let url = URL(string: urlString){

           // 2.  create URL Session- the thing that performs like a browser (default)

            let session = URLSession(configuration: .default)

           // 3.  give session a task;  task waits for data, so uses completion handler

           //     as a function()

            let task = session.dataTask(with: url, completionHandler: handle(data:response:error:))

           // 4.  start the task; "resume" because task is initialized as "suspended"

            task.resume()

        }

    }

    //function to "handle" input to completionHandler in #3; called by the task

    //passes data back to the completionHandler

    func handle(data: Data?, response: URLResponse?, error: Error? ) ->Void {

        //check for errors here

        if error != nil{

            print(error!)

            return  //exit failed

        }

            //optional binding of data

            if let safeData = data {

                //look at data in web data format utc8

                let dataString = String(data: safeData, encoding: .utf8)

                print(dataString)

                

                //new  cll func

                parseJSON(weatherData: safeData)

            }

        //new

        func parseJSON (weatherData: Data) {

           let decoder = JSONDecoder()

            //aski g for a type:  WeatherData is object, WeatherData.self is a type

            //since .decode can throw an error, use a DO  TRY CATCH

            do {

                //.decode creates a WeatherData.self object, so capture it in a constant

            let decodedData = try decoder.decode(WeatherData.self, from: weatherData)

                print("CITY is \(decodedData.name)")

                print(" TEMP IS \(decodedData.main.temp)")

                print("\(decodedData.weather[0].description)")

               

            } catch {

              print(error)

            }


    }

        

        }
