Swift Package Manager (SPM)

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. To integrate using Apple's Swift package manager from xcode :

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

  2. Enter package URL :, 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


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)
      try reachability.startNotifier()
      print("could not start reachability notifier")


@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

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