Check for internet connection in iOS App Swift

Check Internet Connection if you are going in your application, Your Connection are Cellular & WIFI are ON/OFF.

First your create a Network swift class then implement where are you check connection on/off
let start:- a  create public class Reachability 


import Foundation
import UIKit
import SystemConfiguration

public class Reachability {
    
    class func isConnectedToNetwork() -> Bool {
        
        var zeroAddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))
        zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
        zeroAddress.sin_family = sa_family_t(AF_INET)
        
        let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
            $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
                SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
            }
        }
        
        var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0)
        if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false {
            return false
        }
        
        /* Only Working for WIFI
         let isReachable = flags == .reachable
         let needsConnection = flags == .connectionRequired
         
         return isReachable && !needsConnection
         */
        
        // Working for Cellular and WIFI

        let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
        let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
        let ret = (isReachable && !needsConnection)
        
        return ret
        
    }

}


Now implement class Reachability into when open your application - ViewController



 override func viewDidAppear(_ animated: Bool) {
        
        if Reachability.isConnectedToNetwork(){
            print("Internet Connection Available!")
        }else{
            print("Internet Connection not Available!")
            let alert = UIAlertView(title: "No Internet Connection", message:"Make sure your device is connected to the internet", delegate: nil, cancelButtonTitle: "OK")
            alert.show()
        }
    }
