  1. Make sure CocoaPods is installed.

  2. Update your Podfile to include the following:

    use_frameworks!
    pod 'ReachabilitySwift'
    
  3. Run

    pod install
    .
  4. In your code import Reachability like so:

    import Reachability

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To install Reachability.swift with Carthage:

  1. Install Carthage via Homebrew

    bash
    $ brew update
    $ brew install carthage
    
  2. Add

    github "ashleymills/Reachability.swift"
    to your Cartfile.
  3. Run

    carthage update
    .
  4. Drag

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 : 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)
