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.

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:
-
Make sure CocoaPods is installed.
-
Update your Podfile to include the following:
use_frameworks! pod 'ReachabilitySwift'
-
Run
pod install
.
- 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:
- Install Carthage via Homebrew
$ brew update
$ brew install carthage
-
Add
github "ashleymills/Reachability.swift"
to your Cartfile. -
Run
carthage update
. -
Drag
Reachability.framework
from theCarthage/Build/iOS/
directory to theLinked Frameworks and Libraries
section of your Xcode project’sGeneral
settings. -
Add
$(SRCROOT)/Carthage/Build/iOS/Reachability.framework
toInput Files
of Run Script Phase for Carthage. -
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)
