New value is only available in sendAsynchronousRequest - Swift

Question

let bodyData = \"parameter=test\"

let URL: NSURL = NSURL(string: \"Link to php file\")
let request:NSMutableURLRequest = NSMutableURLReque         


        

Answer 1

sendAsynchronousRequest is, as the name suggests, asynchronous. So your final println runs before the request is complete. After the completion handler runs, the new data will be available for all readers (in or outside this handler).
