How to prettyPrint json response from API call in debugger?

Question

Trying to figure out how to prettyPrint the json value of my response from an API, while debugging:

let session = URLSession(configuration: .default)
let task = session.dataTask(with: urlRequest) { data, response, error in
    completion(data, response, error)
}

In the debugger, if I do po data, this is what I get something like this:

How can I print out the actual json structure that is in the data object? Was hoping to see something like this:

{ "firstName" : "John", "lastName" : "Doe", ... }

po debugPrint(data) doesn't output anything in this case.

Answer 1

e print(String(data: JSONSerialization.data(withJSONObject: JSONSerialization.jsonObject(with: data, options: []), options: .prettyPrinted), encoding: .utf8)!)

Answer 2

Try the JSONSerialization, something like this:

let url = URL(string: "http://date.jsontest.com")
var request : URLRequest = URLRequest(url: url!)
request.httpMethod = "GET"

let dataTask = URLSession.shared.dataTask(with: request) {
    data,response,error in
    do {
        if let jsonResult = try JSONSerialization.jsonObject(with: data!, options: []) as? NSDictionary {
            print(jsonResult)
        }
    } catch let error {
        print(error.localizedDescription)
    }
}
dataTask.resume()

Where jsonResult will print out this:

{
    date = "02-19-2018";
    "milliseconds_since_epoch" = 1519078643223;
    time = "10:17:23 PM";
}
