Getting JSON Response from API Swift

Question

At an earlier point today, I was able to use this API and get a response in my iPhone app. The fact that I have been trying to debug this for so long is making be believe that I'm crazy! Attached is a screenshot of my console...

Here is my code pertaining to my API call. Using Apple's URLSession and following many stack overflow questions / Tutorials I can not get this thing to work.

 let task = URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data else {
            print("request failed \(error)")
            return
        }
        do {
            if let json = try JSONSerialization.jsonObject(with: data) as? [String: String], let result = json["result"] {
                // Parse JSON
            }
        } catch let parseError {
            print("parsing error: \(parseError)")
            let responseString = String(data: data, encoding: .utf8)
            print("raw response: \(responseString)")
        }
    }
    task.resume()

Every time I get this interesting [BoringSSL] Error and the searching I've done regarding that has not produced effective in fixing whatever bug I have.

Like I said, earlier today I had this app working using the same API. I have tried the key that the website gave me and the test key they use on their site. Now that I think of it, I am going to use the exact URL from my code and the screenshot and take a screenshot from the response I get in my browser. See below:

Received above response with the exact URL being used in my app.

According to your last screenshot, you don't have a data structure indicated by '[String: String].' — El Tomato

tried your API in my project. It worked. You can check the difference below:

let urlTest = URL(string: "https://www.zipcodeapi.com/rest/wvyR5aWjHNUF80Z6kmr1bTuNojfzhmvtcmfBD8QNo9qbNAHy9FvBISINKF3W5i9J/multi-distance.json/99501/99501,%2085001,%2072201/km")

var request = URLRequest(url: urlTest!)

request.httpMethod = "GET"
let session = URLSession(configuration: .default)

let task : URLSessionDataTask = session.dataTask(with: request) { (data, response, error) in

        let statusCode = (response as! HTTPURLResponse).statusCode
        if statusCode == 200{
            do {
                let json = try JSON(data:data!)
            }
            catch {
                print("Could not convert JSON data into a dictionary.")
            }
        }
    }
    task.resume()

Printing description of json: ▿ { "distances" : { "85001" : 4093.922, "72201" : 4962.6189999999997 } }

It is just for convenience. To get readable data from the response.

May be you have to turn off Transport Layer Security, because that worked for me.

Go to your info.plist file and add a property named App Transport Secrity Settings and set its Allow Arbitrary loads option to NO

Hope this helps.
