Answer 1

Updated for Swift 2. I used the same setup and library for oauth that Qadir describes in his question. I updated his request to work in Swift 2. Hope this helps others.

uberRequest:

    let params:[String:AnyObject] = [
        "product_id" : uberProduct,
        "start_latitude" : userLat,
        "start_longitude" : userLng,
        "end_latitude" : barLat,
        "end_longitude" : barLng]

    let urlPath = "https://sandbox-api.uber.com/v1/requests"
    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
    var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    var session = NSURLSession(configuration: configuration)

    guard let endpoint = NSURL(string: urlPath) else { print("Error creating endpoint");return }

    let request = appDelegate.oauth.request(forURL: NSURL(string:urlPath)!)
    request.setValue("application/json; charset=utf-8", forHTTPHeaderField:"Content-Type")

    request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions.PrettyPrinted)

    request.HTTPMethod = "POST"

    print("Prepare to make request -> \(request)")

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in
        if error != nil{
            print("Error -> \(error)")
            return
        }

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

            print("Result -> \(result)")

        } catch {
            print("Error -> \(error)")
        }
    }

    task.resume()

It returns:

Result -> Optional(["driver": , "request_id": 5834384c-7283-4fe6-88a7-e74150c6ab30, "surge_multiplier": 1, "location": , "vehicle": , "status": processing, "eta": ])
