Internet connectivity: NWPathMonitor

Apple’s Network framework provides a number of useful classes for working with network data, including one specifically designed to monitor network accessibility: NWPathMonitor. If you ever used Apple’s older Reachability system, NWPathMonitor replaces it fully.

import Network
class CheckNetwork {
let monitor = NWPathMonitor()
init(){
monitor.pathUpdateHandler = { path in
if path.status == .satisfied {
print("We're Connected");
}else{
print("No Connection.")
}
print(path.isExpensive)
}
let queue = DispatchQueue(label: "Monitor")
monitor.start(queue: queue);
}
@objc func closeNwConCheck(){
monitor.cancel();
print("closeNwConCheck")
}
}
let nw = CheckNetwork();
