Checking internet connection in swift using Alamofire

I am seeing medium.com as a medium to save my code in remote so that it is accessible from anywhere. This may or may not be helpful for others. :-)

For swift 3+ and Alamofire 4.4 , I created a swift class called Connectivity . You can use NetworkReachabilityManager class from Alamofire and configure the isConnectedToInternet() method as per your need. I am only checking if the device is connected to internet or not.

import Foundation
import Alamofire
class Connectivity {
    class func isConnectedToInternet() ->Bool {
        return NetworkReachabilityManager()!.isReachable
    }
}

Usage:

if Connectivity.isConnectedToInternet() {
        print("Yes! internet is available.")
        // do some tasks..
 }

EDIT: Since swift is encouraging computed properties, you can change the above function like:

import Foundation
import Alamofire
class Connectivity {
    class var isConnectedToInternet:Bool {
        return NetworkReachabilityManager()!.isReachable
    }
}

and use it like:

if Connectivity.isConnectedToInternet {
        print("Yes! internet is available.")
        // do some tasks..
 }

Thanks. !
