How To Check Response.statusCode in sendSynchronousRequest on Swift

How To check response.statusCode in SendSynchronousRequest in Swift The Code is Below :

let urlPath: String = "URL_IS_HERE"
var url: NSURL = NSURL(string: urlPath)
var request: NSURLRequest = NSURLRequest(URL: url)
var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?> = nil

var error: NSErrorPointer? = nil
var data = NSURLConnection.sendSynchronousRequest(request, returningResponse: response, error: nil) as NSData?

before and in objective c , we check response.statusCode With this : (long)response.statusCode but in swift i have no idea how can check response status Code

you pass in a reference to response so it is filled THEN you check the result and cast it to a HTTPResponse as only http responses declare the status code property.

let urlPath: String = "http://www.google.de"
var url: NSURL = NSURL(string: urlPath)
var request: NSURLRequest = NSURLRequest(URL: url)
var response: NSURLResponse?

var data = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: nil) as NSData?

if let httpResponse = response as? NSHTTPURLResponse {
    println("error \(httpResponse.statusCode)")
}

note: in objC you would also use the same approach but if you use squared brackets, the compiler doesn't enforce the cast. Swift (being type safe) does enforce the cast always

Swift 3 version for @GarySabo answer:

let url = URL(string: "https://apple.com")!
let request = URLRequest(url: url)

let task = URLSession.shared().dataTask(with: request) {data, response, error in

    if let httpResponse = response as? HTTPURLResponse {
        print("statusCode: \(httpResponse.statusCode)")
    }

}
task.resume()

Swift 3+

let dataURL = "https://myurl.com"
        var request = URLRequest(url: URL(string: dataURL)!)
        request.addValue("Bearer \(myToken)", forHTTPHeaderField: "Authorization")
        URLSession.shared.dataTask(with: request) { (data, response, error) in
            // Check if the response has an error
            if error != nil{
                print("Error \(String(describing: error))")
                return
            }

            if let httpResponse = response as? HTTPURLResponse{
                if httpResponse.statusCode == 401{
                    print("Refresh token...")
                    return
                }
            }

            // Get data success

        }.resume()

I use an extension to URLResponse to simplify this one (Swift 3):

extension URLResponse {

    func getStatusCode() -> Int? {
        if let httpResponse = self as? HTTPURLResponse {
            return httpResponse.statusCode
        }
        return nil
    }
}
