How To Check Response.statusCode in sendSynchronousRequest on Swift

Question

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

Answer 1

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
