  1. File -> Swift Packages -> Add Package Dependency...

  2. Enter package URL : https://github.com/ashleymills/Reachability.swift, choose the latest release

Example - closures

NOTE: All closures are run on the main queue.

//declare this property where it won't go out of scope relative to your listener let reachability = try! Reachability() reachability.whenReachable = { reachability in if reachability.connection == .wifi { print("Reachable via WiFi") } else { print("Reachable via Cellular") } } reachability.whenUnreachable = { \_ in print("Not reachable") } do { try reachability.startNotifier() } catch { print("Unable to start notifier") }

and for stopping notifications

reachability.stopNotifier()

Example - notifications

NOTE: All notifications are delivered on the main queue.

//declare this property where it won't go out of scope relative to your listener let reachability = try! Reachability() //declare this inside of viewWillAppear NotificationCenter.default.addObserver(self, selector: #selector(reachabilityChanged(note:)), name: .reachabilityChanged, object: reachability) do{ try reachability.startNotifier() }catch{ print("could not start reachability notifier") }

and

@objc func reachabilityChanged(note: Notification) { let reachability = note.object as! Reachability switch reachability.connection { case .wifi: print("Reachable via WiFi") case .cellular: print("Reachable via Cellular") case .unavailable: print("Network not reachable") } }

and for stopping notifications

reachability.stopNotifier() NotificationCenter.default.removeObserver(self, name: .reachabilityChanged, object: reachability)
