An Internet Connectivity class in swift language, to add a check to see if the device is connected to the internet, and an example of how it is implemented in SwiftUI

NetworkMonitor.swift

import Network

class NetworkMonitor: ObservableObject {
    
    @Published var isInternetAvailable = false
    
    init() {
        startMonitoring()
    }
    
    func startMonitoring() {
        let monitor = NWPathMonitor()
        
        monitor.pathUpdateHandler = { path in
            DispatchQueue.main.async {
                self.isInternetAvailable = path.status == .satisfied
            }
        }
        
        let queue = DispatchQueue(label: "Monitor")
        monitor.start(queue: queue)
    }
}

// -------------- You can put these in separate files generally and ContentView is just any sample view

struct ContentView: View { // 
  @StateObject var networkMonitor = NetworkMonitor()
  var body: some View {

  }
  .onReceive(networkMonitor.$isInternetAvailable, perform: { isInternetAvailable in
    if isInternetAvailable {
            //DO WORK
    }
  })
}
