How to use Reachability Objective-C class in Swift

Question

I need to get notified when connectivity changes during app usage. I have imported Reachability.h .m files to my Swift project, and bridged it by adding #include "Reachability.h".

In Apple's Reachability example project an observer is set up to get notified when connectivity changes. How can I set it up in Swift?

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reachabilityChanged:) name:kReachabilityChangedNotification object:nil];

There is no equivalent observer in Swift. Swift has property observers like willSet and didSet.

How do you use `Reachability` in Swift? How do you write `addObserver` line is Swift? — János, Apr 08 '15 at 08:40
NSNotificationCenter.defaultCenter().addObserver(self, selector: "reachabilityChanged:", name: ReachabilityChangedNotification, object: reachability) — Chirag Shah, Apr 08 '15 at 08:42
and why you used objective c Reachability class when there is Reachability in swift — Chirag Shah, Apr 08 '15 at 08:42

Please referred following link for Reachability in swift https://github.com/ashleymills/Reachability.swift

For your add observer please use it like this

NSNotificationCenter.defaultCenter().addObserver(self, selector: "reachabilityChanged:", name: ReachabilityChangedNotification, object: reachability)
