An improved version of @Lachezar's answer for Swift2.x:

Alamofire.request(.POST, url).responseJSON { response in
    switch response.result {
        case .Success(let json):
            // internet works.  
        case .Failure(let error):

            if let err = error as? NSURLError where err == .NotConnectedToInternet {
                // no internet connection
            } else {
                // other failures
            }
    }
}

If you would like the network status without parsing an URL, I suggest this solution: https://stackoverflow.com/a/38646078/706933
