ios - Alamofire -What to do when there is a wifi connection but no internet connection? -

i'm using alamofire in ios app. use bool values in viewwillappear , in appdelegate nsnotifications check if there internet connection. if there no wifi connection pop appears inform user. if there wifi connection pop disappears , works fine again. i've had no problems long wifi not working.

i @ meetup , explained me way works it looks wifi connection , not internet connection. e.g.. if have wifi router , it's plugged in router isn't connected internet alamofire view successful connection because connecting wifi although doesn't know wifi can't connect internet.

i in situation connected open network, app responded if connected internet (no pop up) couldn't connect anything. wifi signal on full. in terminal ran ping , turns out connection dead. app couldn't tell difference.

how make pop appear in sitaution this?

also .case unknown for?

alamofire.swift:

import foundation import alamofire  open class networkmanager {      open static var sharedmanager: networkreachabilitymanager = {          let reachabilitymanager = networkreachabilitymanager()          reachabilitymanager?.listener = { (status) in              switch status {              case .notreachable:                 print("the network not reachable")                 notificationcenter.default.post(name: nsnotification.name(rawvalue: "unsuccessful"), object: nil)              case .unknown : //???????                 print("it unknown wether network reachable")                 //i'm not sure whether put notification successful or unsuccessful???              case .reachable(.ethernetorwifi):                 print("the network reachable on wifi connection")                 notificationcenter.default.post(name: nsnotification.name(rawvalue: "successful"), object: nil)              case .reachable(.wwan):                 print("the network reachable on wwan connection")                 notificationcenter.default.post(name: nsnotification.name(rawvalue: "successful"), object: nil)             }         }          reachabilitymanager?.startlistening()         return reachabilitymanager!     }() } 

appdelegate:

func application(_ application: uiapplication, didfinishlaunchingwithoptions launchoptions: [uiapplicationlaunchoptionskey: any]?) -> bool {          networkmanager.sharedmanager.startlistening() 

somevc:

override func viewwillappear() {         super.viewwillappear()          nsnotificationcenter.defaultcenter().addobserver(self, selector: #selector(successful), name: "successful", object: nil)          nsnotificationcenter.defaultcenter().addobserver(self, selector: #selector(unsuccessful), name: "unsuccessful", object: nil)         if networkmanager.sharedmanager.isreachable == true{             self.successful()        }else{             self.unsuccessful()        }         if networkmanager.sharedmanager.isreachableonwwan == true{              self.successful()        }else{             self.unsuccessful()        }         if networkmanager.sharedmanager.isreachableonethernetorwifi == true{              self.successful()        }else{             self.unsuccessful()        } }  func successful(){     //dismiss pop }  func unsuccessful(){     //show pop }  deinit{     nsnotificationcenter.defaultcenter().removeobserver(self, name: "successful", object: nil)     nsnotificationcenter.defaultcenter().removeobserver(self, name: "unsuccessful", object: nil) } } 

you can init networkreachabilitymanagerwith host, example, google host, because default 0.0.0.0

let reachabilitymanager = alamofire.networkreachabilitymanager(host: "www.google.com") 

when start listening reachability manager doing ping host. if network available can cache ssid , ping again when ssid changed.

for case .unknown better put notification unsuccessful.

example ssid (it doesn't work in simulator):

func fetchssidinfo() ->  string? {           if let interfaces = cncopysupportedinterfaces() {               in 0..<cfarraygetcount(interfaces){                   let interfacename: unsaferawpointer = cfarraygetvalueatindex(interfaces, i)                   let rec = unsafebitcast(interfacename, to: anyobject.self)                   let unsafeinterfacedata = cncopycurrentnetworkinfo("\(rec)" cfstring)                    if let unsafeinterfacedata = unsafeinterfacedata as? dictionary<anyhashable, any> {                       return unsafeinterfacedata["ssid"] as? string                   }               }           }           return nil       }
