How to use NetworkReachabilityManager in Alamofire

Question

I want functionality similar to AFNetworking in Objective-C with Alamofire NetworkReachabilityManager in Swift:

//Reachability detection
[[AFNet

Apple says to use a struct instead of a class when you can. So here's my version of @rmooney and @Ammad 's answers, but using a struct instead of a class. Additionally, instead of using a method or function, I am using a computed property and I got that idea from this Medium post by @Abhimuralidharan. I'm just putting both the idea of using a struct instead of a class (so you don't have to have a singleton) and using a computed property instead of a method call together in one solution.

Here's the struct NetworkState:

import Foundation
import Alamofire

struct NetworkState {

    var isConnected: Bool {
        // isReachable checks for wwan, ethernet, and wifi, if
        // you only want 1 or 2 of these, the change the .isReachable
        // at the end to one of the other options.
        return NetworkReachabilityManager(host: www.apple.com)!.isReachable
    }
}

Here is how you use it in any of your code:

if NetworkState().isConnected {
    // do your is Connected stuff here
}
