I installed Crashlytics on my iOS Today Extension, and I am getting this strange crash. Does anyone know why this might be happening?
Fatal Exception: NSInternalInconsistencyException
removing inactive plug-in com.somecompany.someapp.TodayExtension(1.0)>
The line that it is crashing on is
11 PlugInKit -[PKService unregisterPersonality:] + 188
In my today extension, in viewDidLoad, it will get the user's current location, and then make a network request to fetch data about that location. Is this happening because my operation is taking too long and iOS is killing my extension? I haven't been able to reproduce this, but I think what user's see is a blank space where the extension should be or it doesn't show anything but the title of the extension.

I see exactly the same thing on Crashlytics.
According to Apple this crash is a known bug in iOS 8 (including the 8.3 beta). The crash only occurs when the extension is shutting down, which means that the user doesn't see the extension crash.
So the only thing we can do right now is ignoring this crash

Been trying to recreate and research about this issue for days now and I'm not going anywhere. Here's the stack trace. Can anyone shed light on to what's happening? I take that it has something to do with remote notifications. The issue started a while back when I installed the firebase sdk. Back then it wasn't a lot but now, crashes seem to happen more often than usual.

Is it a known issue to be fixed by apple final non-beta ios 11 release?
Where can i find the MRAVOutputContext reference?

I'm getting many crash reports from my iOS today extension in Crashlytics which I can't make any sense of. The extension retrieves the user's current location and saves it inside the app. The crashes look like this:

As you can see none of my own classes is visible in the stack trace.
How can I debug this? Do these crashes appear to the user?
Thanks for your help!
I am seeing the following crash log in Crashlytics with an iOS app. It is certainly infrequent, and I have been unable to replicate, but it is very annoying.
Anyone able to suggest what this is likely linked to?
