iOS 10 completionHandler called twice?

[mohpor]

I need some help here guys.

My implementation of notifications is very simple:

OneSignal.initWithLaunchOptions(launchOptions, appId: "46b495af-9a8c-4af8-937a-3e57d78a0029", handleNotificationReceived: { result in
      print("Notification received: \(result)")
      guard let typedic = result?.payload.additionalData else {
        print("No additional data found, ignoring notif.")
        return
      }
//...
    }, handleNotificationAction: { result in

      print("Notification opened: \(result)")
     //...
    }, settings: [kOSSettingsKeyInFocusDisplayOption:OSNotificationDisplayType.none.rawValue])

But, when I get the notification in the background and I tap an action button, I get this exception:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'this request has been neutered - you can't call -sendResponse: twice nor after encoding it'

I have searched a lot around and the reason seems to be the fact that the fetchCompletion is getting called twice.

More Details:

• My notification payload is actually contains both contents and content-available, but removing either one didn't help the case.
  Example:

{
  "app_id": "...",
  "included_segments": ["All"],
  "data": {"type":"..."},
  "headings": {"en": "Heading"},
  "subtitle": {"en": "subtitle"},
  "contents": {"en": "body"},
  "buttons": [{"id": "view_button", "text": "details"}]
}

• I have no other code or 3rd party library concerning push notifications whatsoever.
• If I enable in-app notification's alert, the action works perfectly fine.

What am I doing wrong?

@mohpor Thanks for the report. Can you also include the following details.

• iOS version
• OneSignal SDK version
• Full stack trace of the exception.
• Your application:didReceiveRemoteNotification:fetchCompletionHandler: selector code if you have one in your AppDelegate.

[mohpor]

Sure.
iOS: 10.1.1
OneSignal SDK: 2.2.3 (both pod and git head)
Swift Version: 3.0.1
Xcode: Version 8.1 (8B62)
I have no application:didReceiveRemoteNotification:fetchCompletionHandler: selector in my AppDeleagte
Here is the stack trace:

*** Assertion failure in -[UIHandleRemoteNotificationAction sendResponse:withCompletion:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/BaseBoard/BaseBoard-262.2.1/BaseBoard/BSAction.m:438

I'm not sure if this is the FULL stack trace.

Interestingly enough, adding an empty application:didReceiveRemoteNotification:fetchCompletionHandler: to my AppDelegate fixes the problem.

[jkasten2]

@mohpor We made a number of changes around this that should fix this issue in our 2.3.0 release.
https://github.com/OneSignal/OneSignal-iOS-SDK/releases/tag/2.3.0

Could you report back if this version now fixes this issue for you?

[mohpor]

That's great news.
I'm going to test it and report back.

[mohpor]

Well, I still need that empty implemented.

[jkasten2]

Thanks, I am able to reproduce the issue now. Seems only happen when there are action button along with the absents of application:didReceiveRemoteNotification:fetchCompletionHandler:.

I'll be able to create a fix now that I can reproduce the issue.

[mohpor]

That'll be great.

iOS Action Button Crash

[jkasten2]

@mohpor This is now fixed in commit cc7ae43 and will be included in the next release.

[william-normann]

re-open /
We got exactly same issue with @mohpor. But our iOS version is 13.x.x.
We use newest react-native-onesignal with react-native 0.60.6. The native sdk in podspec is 2.11.2.

[namdao]

I have same issue like @mohpor . It crash iOS version 12.x.x. and 13.x.x
I using react-native-onesignal 3.6.0 with react-native 0.60.4. Native sdk is 2.12.2

[william-normann]

@namdao i got no crash since added and empty handler for notification

// this just a workaround to fix onesignal crash in iOS 13+
// need remove when we have a completed solution from OneSignal
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler {
}

@thuan-nguyen-js , I have reproduce and it crash all both. When user minimize app and click noti. Thanks that code which you send. It fixed.
