How to View Response of Posting Data to Yandex API in Swift

manpreet Best Answer 2 years ago

I am trying to post some text for translation to the Yandex translation api using the following method but seem to be getting back invalid JSON. However, I can't read what I'm getting back. Is there a way to parse 'data'? Here is method

func getTranslated(text: String, lang: "en-fr", completion: @escaping (TranslationReturned?) -> Void) {
        guard var components = URLComponents(string: translationUrl) else { return }
        components.queryItems = [URLQueryItem(name: "key", value: translationKey),
                                 URLQueryItem(name: "text", value: text),
                                 URLQueryItem(name: "lang", value: lang),
                                 URLQueryItem(name: "format", value: "plain"),
                                 URLQueryItem(name: "options", value: String(1))]
        var request = URLRequest(url: components.url!)

          request.httpMethod = "POST"

        URLSession.shared.dataTask(with: request) { (data, response, error) in
            print("data in call to yandex is",data as Any)//79 bytes
            if let error = error {
                print("error is",error.localizedDescription)
                completion(nil)
                return
            }

            guard let data = data else {
                print("no data")
                completion(nil)
                return
            }

            do {
                let translation = try JSONDecoder().decode(TranslationReturned.self, from: data)
                completion(translation)
            } catch {
                print(error)
                completion(nil)
            }
            }.resume()
    }

The returned item is 79 bytes long and error is nil but I can't determine what data is. Here is what debugger shows:

data in call to yandex is Optional(79 bytes)
typeMismatch(Swift.String
