Checking for Internet connection does not work

Question

I'm trying to check for the internet connection in my app, and currently, I have this code:

  private let monitor: NWPathMonitor

        monitor.pathUpdateHandler = { [weak self] path in
            print(path.status)
            self?.isConnected = path.status == .satisfied
        }

However, this does not work. Specifically, the print does not print out the value in the debug console.

Could you please tell me what I have done wrong?

Thank you.

you could try removing the `=` such as `monitor.pathUpdateHandler {...}` — workingdog support Ukraine, Dec 21 '21 at 05:53
you will have to show us more of your code for us to help you. Is `monitor` some sort of `model`? Is `pathUpdateHandler` a `var` or a completion handler? etc... In other words: Show a Minimal reproducible example, https://stackoverflow.com/help/minimal-reproducible-example. — workingdog support Ukraine, Dec 21 '21 at 06:04
ok, I see what you are trying to do. I assume you have : `self.monitor = NWPathMonitor()` in the `init()`, is that correct? — workingdog support Ukraine, Dec 21 '21 at 06:13

here is my (SwiftUI, sorry) test code that works for me. You can probably recycle some of the code for your purpose.

import SwiftUI
import Foundation
import Network

@main
struct TestApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

struct ContentView: View {
    let monitor = NWPathMonitor()
    
    var body: some View {
        Text("testing")
            .onAppear {
                let queue = DispatchQueue(label: "monitoring")
                monitor.start(queue: queue)
                monitor.pathUpdateHandler = { path in
                     print(path.status)
                    if path.status == .satisfied {
                        print("-----> YES connected")
                    } else {
                        print("-----> NOT connected")
                    }
                 }
            }
    }
}

You can also use specific monitor, such as let monitor = NWPathMonitor(requiredInterfaceType: .wifi)
