Question

Can I somehow do a synchronous HTTP request via NSURLSession in Swift?

I can do an asynchronous request via the following code:

if let u

Be careful with synchronous requests because it can result in bad user experience but I know sometimes its necessary. For synchronous requests use NSURLConnection:

func synchronousRequest() -> NSDictionary {

        //creating the request
        let url: NSURL! = NSURL(string: "exampledomain/...")
        var request = NSMutableURLRequest(URL: url)
        request.HTTPMethod = "GET"
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")


        var error: NSError?

        var response: NSURLResponse?

        let urlData = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)

        error = nil
        let resultDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(urlData!, options: NSJSONReadingOptions.MutableContainers, error: &error) as! NSDictionary

        return resultDictionary
    }
