I've read about the woes of silent push notifications in iOS, so this will likely be fruitless ... but I figure I'll ask if only to just maybe have an Apple rep see it.

I'm sending a simple APNS message to an iOS 8.1 app:

    aps: {
        content-available: 1,
        priority: 5
    }

The app is in the background (read: I have not force-closed it).

Sometimes my app delegate's didReceiveRemoteNotification with fetchCompletionHandler fires, sometimes it doesn't. I can tell because I am monitoring my server and can see if/when a GET request arrives.

I'm currently exploring if there's a correlation with passing weather systems and/or bird migration patterns.

But what's really frustrating is that when I build/launch my app via xCode, here's the console output:

- appDelegate: received notification
- appDelegate: fetching stories
- appDelegate: application launched
- appDelegate: remote notifications approved
 **** modal view controller: viewDidLoad

Notice the notification is "received" just as xCode is firing up the app, but before the application launches (?).

It's as though the device is receiving silent notifications but is sitting on them until xCode starts the app. Additionally, I've noticed that when the device is running the app & connected to xCode, silent push notifications arrive very reliably ... which would also suggest some sort of irregularity involving xCode.

Am I doing something wrong? Is anyone else seeing this phenomenon? Or is this just a bug with iOS / APNS?

I'm happy to try out any code snippets or suggestions anyone has! Thank you.

  • @user3703910 Could you clarify which part of that thread you're referencing? I read that before writing my question, but perhaps there's a part that I missed? I am *not* force-closing my app (it's running in the background). – Dan Dec 30 '14 at 02:09
  • I also noticed that when I have my app running via Xcode to my device -- that it always receives the silent notifications. However, when I test it just via my device (without xcode) -- sometimes i get different results -- where the notification doesn't show up (even though I did not force-close my app). – Sandy D.
