Reachability

Reachability.swift

Replacement for Apple's Reachability re-written in Swift with callbacks

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

NOTE:

As of Swift 1.1, you cannot convert Swift closures into C-function pointers, meaning we can't set an SCNetworkReachabilityCallBack.

To get around this, this reachability replacement uses an NSTimer firing at 1/2 second intervals.

Use

Just drop the Reachability.swift file into your project. That's it!

Example - closures

let reachability = Reachability.reachabilityForInternetConnection()

reachability.whenReachable = { reachability in
    if reachability.isReachableViaWiFi() {
        println("Reachable via WiFi")
    } else {
        println("Reachable via Cellular")
    }
}
reachability.whenUnreachable = { reachability in
    println("Not reachable")
}

reachability.startNotifier()

Example - notifications

let reachability = Reachability.reachabilityForInternetConnection()

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

reachability.startNotifier()

and

func reachabilityChanged(note: NSNotification) {

    let reachability = note.object as Reachability

    if reachability.isReachable() {
        if reachability.isReachableViaWiFi() {
            println("Reachable via WiFi")
        } else {
            println("Reachable via Cellular")
        }
    } else {
        println("Not reachable")
    }
}

If you use Reachability.swift, please let me know… and tell your friends!
