Answer 1

Using Alamofire to send HTTP POST request

let request = NSMutableURLRequest(URL: NSURL(string: "https://www.google.com")!)
request.HTTPMethod = "POST"

let body = "email=\(email)&access_token=\(token)"
request.HTTPBody = body.dataUsingEncoding(NSUTF8StringEncoding)

Alamofire.request(request).responseJSON { response in

        NSLog("response.request: \(response.request)")  // original URL request
        NSLog("esponse.response: \(response.response)") // URL response

        switch response.result {
        case .Success:
            NSLog("Validation Successful")
        case .Failure(let error):
            // Logout
            NSLog("\(error), \(String(data: response.data!, encoding: NSUTF8StringEncoding))")
            return
        }

        // Save sip account information to NSUserdefaults
        if let json = response.result.value as? [String: AnyObject]{
            // Do your stuff
        } 
}

stringByAddingPercentEscapesUsingEncoding returns a string instead of an NSData object. According to this answer, you need to use this to convert to an NSData instance:

let data = (anySwiftString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
