Usage

Example - notifications

NOTE: All notifications are delivered on the main queue.

let token = NWReachability.default.addObserver { [weak self] connectivity in
 print("connectivity isConnected \(connectivity.isConnected)")
 print("connectivity isExpensive \(connectivity.isExpensive)")
 switch connectivity.status {
 case .reachable(.cellular):
   print("cellular")
 case .notReachable:
   print("notReachable")
 case .reachable(.ethernetOrWiFi):
   print("ethernetOrWiFi")
case .unknown:
   print("unknown")
}
}
NWReachability.default.startMonitoring()

and for stopping notifications

NWReachability.default.stopMonitoring()
NotificationCenter.default.removeObserver(token as Any)

Example - Combine

NWReachability.default.publisher.sink {  [weak self] connectivity in
  print("connectivity isConnected \(connectivity.isConnected)")
  print("connectivity isExpensive \(connectivity.isExpensive)")
  switch connectivity.status {
  case .reachable(.cellular):
    print("cellular")
  case .notReachable:
    print("notReachable")
  case .reachable(.ethernetOrWiFi):
    print("ethernetOrWiFi")
  case .unknown:
    print("unknown")
  }          
}.store(in: &cancellables)
