Unable to POST a request in swift

Question

    let urlString = "https://192.168.1.167:8090/Attendance/register"

    let url = NSURL(string: urlString)



    let theRequest = NSMutableURLRequest(URL: url!)

    theRequest.HTTPMethod = "POST"


    let parameters = ["firsrtName": regFirstNameTxtField.text!, "lastName": regLastNameTxtField.text!,"email": regEmailTxtField.text!,"password": regPassWordTxtField.text!,"phone": regPhoneNoTxtField.text!] as Dictionary<String, String>

    var err: NSError?

    do {
        theRequest.HTTPBody = try NSJSONSerialization.dataWithJSONObject(parameters, options: [])
    } catch let error as NSError {
        err = error
        theRequest.HTTPBody = nil
    } // pass dictionary to nsdata object and set it as request body

    theRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
    theRequest.addValue("application/json", forHTTPHeaderField: "Accept")


    var connectRequest  = NSURLConnection(request: theRequest, delegate: self)

I am unable to post a request in swift. It worked perfectly with my older version of xcode. But now when I run it shows the following error message : UserInfo={NSLocalizedDescription=An SSL error has occurred and a secure connection to the server cannot be made.,
