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 - 10.0), OSX (10.9 - 10.12) and tvOS (9.0 - 10.0)

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

IMPORTANT

Supporting Swift 2.3 and Swift 3

The source has been updated to support both Swift 2.3 (tag v2.4) and Swift 3 (tag v3.0)

To install Reachability.swift for Swift 2.3 using CocoaPods, include the following in your Podfile

'ReachabilitySwift', '~> 2.4'

To install Reachability.swift for Swift 3.x using CocoaPods, include the following in your Podfile

'ReachabilitySwift', '~> 3'

Swift 3 breaking changes

Previously:

s func reachabilityForInternetConnection() throws

Now:

?()

Previously:

(hostname: String) throws

Now:

?(hostname: String)

Previously:

ic enum NetworkStatus: CustomStringConvertible {
case NotReachable, ReachableViaWiFi, ReachableViaWWAN

Now:

ic enum NetworkStatus: CustomStringConvertible {
case notReachable, reachableViaWiFi, reachableViaWWAN

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'd like to help keep me motivated, please download my free app, Foto Flipper from the App Store. (To really motivate me, pay $0.99 for the IAP!)

And don't forget to ? the repo. This increases its visibility and encourages others to contribute.

Thanks Ash

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:

   frameworks!
   'ReachabilitySwift'
   

3. Run pod install.

4. In your code import Reachability like so: import ReachabilitySwift

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

   ew update
   ew 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.

Example - closures

clare this property where it won't go out of scope relative to your listener
reachability = Reachability()!

hability.whenReachable = { reachability in
// this is called on a background thread, but UI updates must
// be on the main thread, like this:
dispatch_async(dispatch_get_main_queue()) {
    if reachability.isReachableViaWiFi() {
        print("Reachable via WiFi")
    } else {
        print("Reachable via Cellular")
    }
}

hability.whenUnreachable = { reachability in
// this is called on a background thread, but UI updates must
// be on the main thread, like this:
dispatch_async(dispatch_get_main_queue()) {
    print("Not reachable")
}



try reachability.startNotifier()
tch {
print("Unable to start notifier")

and for stopping notifications

hability.stopNotifier()

Example - notifications

This sample will use NSNotifications to notify when the interface has changed. They will be delivered on the MAIN THREAD, so you can do UI updates from within the function.

clare this property where it won't go out of scope relative to your listener
reachability = Reachability()!

clare this inside of viewWillAppear

 NotificationCenter.default.addObserver(self, selector: #selector(self.reachabilityChanged),name: ReachabilityChangedNotification,object: reachability)
do{
  try reachability.startNotifier()
}catch{
  print("could not start reachability notifier")
}

and

 reachabilityChanged(note: NSNotification) {

t reachability = note.object as! Reachability

 reachability.isReachable {
if reachability.isReachableViaWiFi {
  print("Reachable via WiFi")
} else {
  print("Reachable via Cellular")
}
else {
print("Network not reachable")

and for stopping notifications

hability.stopNotifier()
tificationCenter.defaultCenter().removeObserver(self,
                                                name: ReachabilityChangedNotification,
                                                object: reachability)
