NetworkMonitor

A solution that monitors and reacts to network connectivity changes 🌦️.

Requirements

• iOS 12 and later
• macOS 10.14 and later

Install

Add https://github.com/henriquestiagoo/network-monitor in the “Swift Package Manager” tab in Xcode.

Usage

You can initiate the monitoring process by making a call to NetworkMonitor.shared.startMonitoring() from any location within your code. However, in most cases, it is a good idea to initiate this process in the AppDelegate.

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?

    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions:
        [UIApplication.LaunchOptionsKey: Any]? = nil
    ) -> Bool {
    
        // start monitoring network changes
        NetworkMonitor.shared.startMonitoring()

        return true
  }
}

After that, you can use NetworkMonitor.shared.isConnected to check the real-time status of you network connection.

import NetworkMonitor

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        NotificationCenter.default.addObserver(
            self, 
            selector: #selector(connectivityStatusChanged(notification:)), 
            name: Notification.Name.connectivityStatusChanged, 
            object: nil
        )
    }

    @objc func connectivityStatusChanged(notification: Notification) {
        if NetworkMonitor.shared.isConnected {
            print("Connected")
        } else {
            print("Not connected")
        }
    }
}

A DispatchQueue is being used to manage the network changes, so don't forget to switch to the Main Thread if you want to update the UI.

Note

You may find unexpected results using the simulator. I recommend, if possible, to test in a real device.
