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

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.

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

   $ 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

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)
