base on Replacement for Apple's Reachability re-written in Swift with closures # 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. Please consider sponsoring me https://github.com/sponsors/ashleymills, it's a great way to say thanks!

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: ``` ruby use_frameworks! pod 'ReachabilitySwift' ``` 3. Run `pod install`. [CocoaPods]: https://cocoapods.org [CocoaPods Installation]: https://guides.cocoapods.org/using/getting-started.html#getting-started 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 `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` [Carthage]: https://github.com/Carthage/Carthage [Homebrew]: http://brew.sh [Photo Flipper]: https://itunes.apple.com/app/apple-store/id749627884?pt=215893&ct=GitHubReachability&mt=8 ### 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**. ```swift //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 ```swift reachability.stopNotifier() ``` ## Example - notifications NOTE: All notifications are delivered on the **main queue**. ```swift //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 ```swift @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 ```swift reachability.stopNotifier() NotificationCenter.default.removeObserver(self, name: .reachabilityChanged, object: reachability) ``` ## Want to help? Got a bug fix, or a new feature? Create a pull request and go for it! ## Let me know! If you use **Reachability.swift**, please let me know about your app and I'll put a link [here…](https://github.com/ashleymills/Reachability.swift/wiki/Apps-using-Reachability.swift) and tell your friends!
