So i am trying to monitor the connection status by closers :
func reconnect(success: @escaping () -> Void, failure: @escaping () -> Void) {
let manager = NEHotspotConfigurationManager.shared
let ssid = CameraManager.camera.uuid
let password = "password"
let isWEP = false
let hotspotConfiguration = NEHotspotConfiguration(ssid: ssid, passphrase: password, isWEP: isWEP)
hotspotConfiguration.joinOnce = true
manager.apply(hotspotConfiguration) { (error) in
if (error != nil) {
if let error = error {
switch error._code {
case 8:
print("internal error")
failure()
case 7:
NotificationCenter.default.post(name: Notification.Name(rawValue: "cancelFromHotSpot"), object: nil)
failure()
self.stopSession()
case 13:
success()
DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) {
self.startSession()
}
default:
break
}
}
if error == nil {
print("success connecting wifi")
success()
DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) {
self.startSession()
}
}
}
}
Yet there is a scenario that i am getting this alert "Unable to join the network" while error is nil, any ideas?
I think this behavior is a iOS bug and we cannot avoid.
This problem was also discussed in Apple Developer Forum and answer of Apple staff was below
"I’ve got nothing to say here beyond what I said on 13 Feb. The fact that errors from the Wi-Fi subsystem don’t get reported via the completion handler is expected behaviour. If you don’t like that behavior — and, to be clear, I personally agree with you about that — the best way forward is to file a bug report requesting that it be changed. Please post your bug number, just for the record."
So I do not have great ideas, unfortunately. All ideas I have are two below (these do not solve this problem perfectly.)
@IBAction func setConfigurationButtonTapped(_ sender : Any) {
manager.apply(hotspotConfiguration) { (error) in
if(error != nil){
// Do error handling
}else{
// Wait a few seconds for the case of showing "Unable to join the..." dialog.
// Check reachability to the device because "error == nil" does not means success.
}
}
@IBAction func sendButtonTapped(_ sender : Any) {
self.startSession()
}
