Reachability.swift | Replacement for Apple 's Reachability re-written in Swift | iOS library

I was in a situation where the router with the wifi was plugged in but the router wasn't connected to the internet (no wifi). Whatever reachability class I was using at the time thought it was connected because wifi was available but it couldn't determine that the wifi itself couldn't get a connection.

I now use Ashley Mills Reachability and it works fine because it can tell wether I'm connected to the internet or not by pinging a host name.

I have 2 versions of Xcode installed, 8.3.2 and 8.2.1.

I'm working on a project that was written in Swift 2 and installed few third-party's via Carthage. After pulling branch I did carthage update : then I got this error:

I am using Reachability.swift to test the internet connection is (off/On) and the server is (live/dead) the server check work fine but internet Connection is always giving me false?

I am using this lib for checking Reachability

And below is my sample code:

I have a set up, using Ashley Mills Reachability, which is supposed to send a notification, using NotificationCenter, to the application when the connection of the app changes. It is set up as follows:

I am working on a complex app and I want to test both host in internet reachability on each ViewController that receive data from server I am currently using this library for Reachability

https://github.com/ashleymills/Reachability.swift

And I want to create an easy method or extension that check the reachability for both internet and host out of this I have already use the sample code from the library which is below: `import UIKit

In my Podfile, I have:

For Swift 4/xcode:
I have scoured the internet for a solution to this issue, but I have yet to find a definitive, comprehensive answer that covers all of the bases. There are several on Stack that answer the question to some extent, including swift specific answers such as these or AshleyMills Reachability, but many are old and not comprehensive.
1. I want the method to check for internet connection, not just connection to wifi. Several of the methods online merely check for connection to Wi-Fi, but do not confirm that internet is available via the wifi. I want a method that only returns true if internet connection is detected.
2. This method must also return true for cellular data usage. Yes Wi-Fi can provide internet connection, but so can data. This method needs to be comprehensive enough to return true if either or both cellular/wifi internet is provided.
Lastly, a note. The fact that there isn't a full swift answer online that checks all of the boxes makes me wonder if my approach to this issue is incorrect in a more general sense. My app needs to load data from a database, which is why it needs the internet connection. This is an extremely common thing for popular apps nowadays. Apps don't crash from trying to load their data without internet connection. What I am thinking they do (which is the basis for this question) is as so:

I downloaded the iOS sample Reachability project from AshleyMills Reachability

It has a networkStatus label that says either: Wifi or No Connection

Underneath that it has a hostNameLabel that says either: No host name or google.com or invalidhost

When I run the app on my device it repeatedly cycles the connection every 5 seconds in the following manner:

1st 5 secs:

2nd 5 sec:

3rd 5 secs:

Start cycle over from 1st, 2nd, and 3rd all over again and keep repeating.

I'm on Home wifi and my internet connection is strong (no problems with any other apps). Why does it continuously cycle like this instead of just staying on Wifi + google.com (the 2nd cycle)
