Swift 3:

// handle basic connectivity issues here
guard error == nil else {
    print("Error: ", error!)
    return
}

// handle HTTP errors here
if let httpResponse = response as? HTTPURLResponse {
    let statusCode = httpResponse.statusCode

    if (statusCode != 200) {
        print ("dataTaskWithRequest HTTP status code:", statusCode)
        return;
    } 
}

}
