Reachability.swift

Reachability.swift is a replacement for Apple's Reachability sample, re-written in Swift with closures.

It is compatible with iOS (8.0 - 12.0), OSX (10.9 - 10.14) and tvOS (9.0 - 12.0)

Inspired by https://github.com/tonymillion/Reachability

Supporting Reachability.swift

Keeping Reachability.swift up-to-date is a time consuming task. Making updates, reviewing pull requests, responding to issues and answering emails all take time.

If you're an iOS developer who's looking for a quick and easy way to create App Store screenshots, please try out my app Screenshot Producer

Installation

Manual

Just drop the Reachability.swift file into your project. That's it!

CocoaPods

[CocoaPods][] is a dependency manager for Cocoa projects. To install Reachability.swift with CocoaPods:

  1. Make sure CocoaPods is [installed][CocoaPods Installation].

  2. Update your Podfile to include the following:

    use_frameworks!
    pod 'ReachabilitySwift'
  3. Run pod install.

  1. 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][]

    $ brew update
    $ brew install carthage
  2. Add github "ashleymills/Reachability.swift" to your Cartfile.

  3. Run carthage update.

  4. Drag Reachability.framework from the Carthage/Build/iOS/ directory to the Linked Frameworks and Libraries section of your Xcode project’s General settings.

  5. Add $(SRCROOT)/Carthage/Build/iOS/Reachability.framework to Input Files of Run Script Phase for Carthage.

  6. In your code import Reachability like so: import Reachability

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 = 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 = 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)
