I have used the following code for connecting to the proxy server and works great for only HTTP requests but not for HTTPS. In iOS 9.0, kCFStreamPropertyHTTPSProxyHost and kCFStreamPropertyHTTPSProxyPort are depreciated.
let myPortInt = 12345;
let myProxyUrlString = "myProxyURL";
let sessionConfiguration = NSURLSessionConfiguration.defaultSessionConfiguration();
sessionConfiguration.connectionProxyDictionary = [
kCFNetworkProxiesHTTPEnable: true,
kCFNetworkProxiesHTTPPort: myPortInt,
kCFNetworkProxiesHTTPProxy: myProxyUrlString,
]
let url = NSURL(string: endPointUrl)
let postRequest = NSMutableURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData, timeoutInterval: 10.0)
let jsonString = bodyString
postRequest.HTTPBody = jsonString
postRequest.HTTPMethod = "POST"
postRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
let session = NSURLSession(configuration: sessionConfiguration)
let task = session.dataTaskWithRequest(postRequest){}
