Add observer to internet connection in Swift

Add observer to internet connection

Suppose you want to check that your internet connectivity changes when it turns on /off in your application.You have to add the observer to your application of checking that it tells you that your internet connection is on or off. Follow this code to check

 func applicationDidBecomeActive(_ application: UIApplication) {
         self.startMonitoring()
 }

func startMonitoring() {
        let reachability = Reachability()!
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(self.reachabilityChanged),
                                               name: ReachabilityChangedNotification,
                                               object: reachability)
        do{
            try reachability.startNotifier()
            print("dfdffdeffeffefef")
        } catch {
            print("Could not start reachability notifier")
        }
    }

func applicationDidBecomeActive(_ application: UIApplication) {

self.startMonitoring()

}

func startMonitoring() {

let reachability = Reachability()!

NotificationCenter.default.addObserver(self,

selector: #selector(self.reachabilityChanged),

name: ReachabilityChangedNotification,

object: reachability)

do{

try reachability.startNotifier()

print("dfdffdeffeffefef")

} catch {

print("Could not start reachability notifier")

}

This will start monitoring internet connection . to check your connection follow :-

 func reachabilityChanged(notification: Notification) {
        
        let reachability = notification.object as! Reachability
        switch reachability.currentReachabilityStatus {
        case .notReachable:
            print("Network became unreachable")
        case .reachableViaWiFi:
            print("Network reachable through WiFi")
        case .reachableViaWWAN:
            print("Network reachable through Cellular Data")
        }
    }

func reachabilityChanged(notification: Notification) {

let reachability = notification.object as! Reachability

switch reachability.currentReachabilityStatus {

case .notReachable:

print("Network became unreachable")

case .reachableViaWiFi:

print("Network reachable through WiFi")

case .reachableViaWWAN:

print("Network reachable through Cellular Data")

}
