Swift Package: NetworkMonitor

In this post, we will explore a Swift package designed to monitor network connectivity in iOS applications.

What is NetworkMonitor?

NetworkMonitor is a Swift package that provides a simple way to monitor the network connectivity status of your iOS app. This can be particularly useful for applications that rely on network access to function properly.

Installation

To install NetworkMonitor, you can use the Swift Package Manager. Add the following line to your Package.swift file:

.package(url: "https://github.com/0xWDG/NetworkMonitor", branch: "main")

Then, add NetworkMonitor to the dependencies of your target:

.target(
    name: "YourApp",
    dependencies: ["NetworkMonitor"]),

Use Case

Sometimes, you may want to perform certain actions based on the network connectivity status. For example, you might want to show a "No Internet Connection" screen when the user is offline or retry a network request when the connection is restored.

import SwiftUI
import NetworkMonitor

struct ContentView: View {
    @ObservedObject
    private var network = NetworkMonitor()

    var body: some View {
        VStack {
            Text("Hello!")
            Text("The network status is \(network.isConnected ? "Connected" : "Disconnected")")
            Text("You are using a \"\(network.isExpensive ? "Expensive" : "Normal")\" internet connection")

            HStack(spacing: 0) {
                Text("You are using \"")
                switch (network.networkType) {
                case .cellular:
                    Text("Celluar")
                case .wifi:
                    Text("Wifi")
                case .loopback:
                    Text("Loopback")
                case .other:
                    Text("Other")
                case .wiredEthernet:
                    Text("Wired")
                default:
                    Text("Unknown")
                }
                Text("\" to connect to the internet")
            }
        }.task {
            print(network.nwPath)
        }
    }
}

Caveats

While NetworkMonitor can be a useful tool for monitoring network connectivity, it's important to keep in mind that it may not cover all edge cases. For example, changes in network status may not be immediately reflected in the UI, and there may be a delay between when the network status changes and when the app is notified of the change. Additionally, the package may not account for all possible network configurations and scenarios.

Wrap up

In summary, NetworkMonitor is a valuable tool for developers looking to enhance the network connectivity monitoring capabilities of their iOS applications. By providing a simple and effective way to track network status changes, it can help improve the overall user experience and ensure that your app behaves as expected in different network conditions.
