Unable to receive VoIP notification using PushKit - ios

Question

I am following this article and M Penades' answer building VoIP Notification Demo. I am able to register notification using didRegisterUserNotificationSettings and can get voip token from didUpdatePushCredentials.
But when I am using houston simulates sending notification to my device, I can get 1 push notification sent successfully message from console but no actions or logs on device side. It seems that didReceiveIncomingPushWithPayload never invoked.
P.S. I am using Xcode 7.3, iPhone 6(iOS 9.3) and iPad Mini(iOS 9.3) for development. Distributed Ad Hoc ipa for installation.
The codes posted here.
import UIKit
import PushKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let voipRegistry = PKPushRegistry(queue: dispatch_get_main_queue())
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//Enable all notification type. VoIP Notifications don't present a UI but we will use this to show local nofications later
let notificationSettings = UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound] , categories: nil)
//register the notification settings
application.registerUserNotificationSettings(notificationSettings)
//output what state the app is in. This will be used to see when the app is started in the background
NSLog("app launched with state \(application.applicationState.stringValue)")
return true
}
func applicationWillTerminate(application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
//output to see when we terminate the app
NSLog("app terminated")
}
}
extension AppDelegate {
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
//register for voip notifications
NSLog("didRegisterUserNotificationSettings called")
voipRegistry.desiredPushTypes = Set([PKPushTypeVoIP])
voipRegistry.delegate = self;
}
}
extension AppDelegate: PKPushRegistryDelegate {
func pushRegistry(registry: PKPushRegistry!, didUpdatePushCredentials credentials: PKPushCredentials!, forType type: String!) {
NSLog("didUpdatePushCredentials called")
//print out the VoIP token. We will use this to test the nofications.
NSLog("voip token: \(credentials.token)")
}
func pushRegistry(registry: PKPushRegistry!, didReceiveIncomingPushWithPayload payload: PKPushPayload!, forType type: String!) {
NSLog("didReceiveIncomingPushWithPayload called")
let payloadDict = payload.dictionaryPayload["aps"] as? Dictionary<String, String>
let message = payloadDict?["alert"]
//present a local notifcation to visually see when we are recieving a VoIP Notification
if UIApplication.sharedApplication().applicationState == UIApplicationState.Background {
NSLog("incoming notificaiton from background")
let localNotification = UILocalNotification();
localNotification.alertBody = message
localNotification.applicationIconBadgeNumber = 1;
localNotification.soundName = UILocalNotificationDefaultSoundName;
UIApplication.sharedApplication().presentLocalNotificationNow(localNotification);
}
else {
NSLog("incoming notificaiton from frontend")
dispatch_async(dispatch_get_main_queue(), { () -> Void in
let alertController = UIAlertController(title: "Title", message: "This is UIAlertController default", preferredStyle: UIAlertControllerStyle.Alert)
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil)
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil)
alertController.addAction(cancelAction)
alertController.addAction(okAction)
UIApplication.sharedApplication().keyWindow?.rootViewController?.presentViewController(alertController, animated: true, completion: nil)
})
}
NSLog("incoming voip notfication: \(payload.dictionaryPayload)")
}
func pushRegistry(registry: PKPushRegistry!, didInvalidatePushTokenForType type: String!) {
NSLog("didInvalidatePushTokenForType called")
NSLog("token invalidated")
}
}
extension UIApplicationState {
//help to output a string instead of an enum number
var stringValue : String {
get {
switch(self) {
case .Active:
return "Active"
case .Inactive:
return "Inactive"
case .Background:
return "Background"
}
}
}
}
Any idea on how to receive such notification?

Finally I fixed this issue.
There is ok for swift source code, the issue is I mis-send the push request to apple's development server gateway.sandbox.push.apple.com, actually we should send request to apple's production server gateway.push.apple.com.
If you are following M Penades' procedure, please note that you need modify Simplepush script, just replace ssl://gateway.sandbox.push.apple.com:2195 by ssl://gateway.push.apple.com:2195 at line 20 and try again.
Hope it works for you.
