IBM Swift Sandbox: starting NSURLSession: error starting code: unknown error code 132

Question

I am trying to execute the following script:

import Foundation

class TestURLSession{

var session: NSURLSession!

func run(){
    session = NSURLSession.sharedSession()

    let url = NSURL(string: "http://www.veenex.de/tmp/json")
    let request = NSMutableURLRequest(URL: url!)
    request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.HTTPMethod = "GET"

    let getDataTask = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in

        // HTTP Response contains an error
        if let httpResponse = response as? NSHTTPURLResponse {
            if httpResponse.statusCode != 200 {
                print("response was not 200: \(response)")
                return
            }
        }

        // Error submitting Request
        if error != nil {
            print("error submitting request: \(error)")
            return
        }

        // print data
        if data != nil{

            do {
                let json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as! NSArray

                for entry in json {
                    print(entry)
                }

            } catch {
                print("Error printing data")
            }

        }


    });

    getDataTask.resume()
}

}

let testURLSession = TestURLSession()
testURLSession.run()

But I get the error message: "Error starting code: unknown error code 132.". Code execution on the Xcode playground works.

Answer 1

A pure Swift implementation NSURLSessionhas not yet been written. Browse the NSURLSession.swiftfile on the Apple GitHub repo for Foundation.

Each method NSUnimplemented(), which means that it is not yet implemented. Until this class is completed, it will not be available for use on Linux and IBM Swift Sandbox.
