How To Check Response.statusCode in sendSynchronousRequest on Swift

by

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
