Platform(s)

Tested on iPhone 7 Plus with iOS 13.5.1

Current Behavior

1. Launch the app, wait for the home screen to be displayed, then put it in the background
2. Push a notification to the app
3. None of the app callbacks get called

Expected Behavior

1. At least the pushNotificationReceived callback get called

Code Reproduction

Use the example guide to create a demo app, then try to send the following notification payloads (I tried both a "normal" payload and a "background mode" payload, see docs here):

normal payload

{
  "APNS_SANDBOX": {
    "aps":{
      "alert":{
        "title": "A title", 
        "body":"A notification for you"
      },
      "sound":"default"
    },
    "additionalData": "my additional data"
  }
}

background mode payload

{
  "APNS_SANDBOX": {
    "aps":{
      "content-available": 1
    },
    "additionalData": "my additional data"
  }
}

Other Technical Details

npm --version output: 6.13.4

node --version output: v12.16.1

pod --version output (iOS issues only): 1.9.1

Additional Context

pushNotificationReceived is only fired if the app is in foreground, if in background the OS will display the push notification and if you tap it pushNotificationActionPerformed will be called.

Silent push are not supported by Capacitor push plugin

[sertal70]

thank @jcesarmobile for your answer, I'll switch back my app to Cordova push plugin.

I'm in the process to migrate an app from Ionic3+Cordova to Ionic5+Capacitor, at the end of the journey this will result in a mixed Capacitor+Cordova app, a very unpleasant result.

If Capacitor does not implement the "feature parity" toward Cordova and its plugin ecosystem, then the Ionic team should avoid to advertise Capacitor as a Cordova replacement, because it is not.

Hello @jcesarmobile Is there a plan to update Capacitor push to support silent push for IOS?
@sertal70 Which plugin do you recommend to use? I'm new to Ionic and I'd appreciate if you could send me a link to cordova push plugin.
