You cause following swift code to get the final redirected url:

            let request = NSMutableURLRequest(url: url, cachePolicy: .reloadIgnoringCacheData, timeoutInterval: 15.0)
        request.httpMethod = "HEAD"
        var response: URLResponse? = nil
        do {
            try NSURLConnection.sendSynchronousRequest(request as URLRequest, returning: &response)
        } catch { //Handle exception //if any
        }
        let finalURL = response?.url
